🏆 Best Anker Solar Generators UK – Our Top Picks
These are my top picks for the best Anker solar generators UK buyers should consider. Each Anker SOLIX unit is a portable power station that can also be used as a solar generator when paired with compatible solar panels.
Anker’s SOLIX range now covers everything from compact portable power stations for camping and travel to much larger systems designed for home backup and longer outages.
The lineup can be a little confusing because the newer S2000 sits alongside the C-Series rather than simply replacing it. The C models generally focus more on mainstream portable performance and higher appliance output, while the S2000 takes a different approach with a lighter 2kWh design and an emphasis on efficiency and battery longevity.
In this guide, I compare the main Anker portable power stations worth considering in the UK, including the C300X, C1000 Gen 2, S2000, C2000 Gen 2 and F3000.
A note on testing: I’ve now bought the Anker SOLIX S2000 for my own use, although I haven’t completed a full hands-on review yet. I’ll update this guide and publish a dedicated review once I’ve tested charging, runtime, solar input and everyday use properly.

Anker SOLIX Portable Power Station Comparison
The table below compares the main Anker SOLIX models I think are most worth considering, from the compact C300X through to the much larger F3000.
Capacity tells you roughly how long the battery can run your equipment, while AC output determines how demanding an appliance the power station can support. Solar input, weight and expandability also become increasingly important as you move up the range.
Which Anker SOLIX Is Best for You?
The comparison table shows the main differences, but the right choice depends on how much capacity you need, what appliances you want to run and how portable the unit needs to be.
Below, I take a closer look at each of the four models, starting with the compact C300X and working up to the much larger F3000.
The Anker SOLIX C300X is the model I would choose when portability matters most. It has a 288Wh LiFePO₄ battery, 300W continuous AC output and up to 100W of solar input, while remaining small enough to carry easily.
That makes it very different from Anker’s larger SOLIX models. Rather than trying to provide long-duration household backup, the C300X is designed around camping, travel, charging electronics and giving you a compact source of mains-style power when you are away from a socket.
Compact Battery for Everyday Devices
A 288Wh battery is obviously limited compared with a 1kWh or 2kWh portable power station, but it is still enough for many of the devices people actually take camping or use during a short power cut.
Phones, tablets, laptops, cameras, lighting, routers and other lower-powered electronics are realistic uses. The main limitation is the 300W continuous AC output, so I would not buy it expecting to run kettles, heaters or other high-draw household appliances.
100W Solar Input
The C300X accepts up to 100W of solar input, which is reasonably well matched to its small battery capacity.
A compact portable panel can therefore provide a useful way to recharge it while camping or travelling without needing the much larger solar arrays that make more sense with Anker’s 1kWh, 2kWh and 3kWh models.
Designed to Be Carried
The biggest advantage of the C300X is simply that it is genuinely portable. At around 4.1kg, it is easy to move between the house, car, campervan, garden or campsite.
That distinction becomes important as you move up the SOLIX range. The C1000 Gen 2 is still reasonably manageable, but the S2000 and larger models are better thought of as batteries you can move when needed rather than something you would want to carry around regularly.
Who Is the Anker SOLIX C300X Best For?
I think the C300X makes most sense for camping, travel, laptops, photography equipment, charging devices and light emergency backup. Its small size and low weight are more important here than having a large battery or high inverter output.
If you mainly want USB and DC power and do not need a normal AC socket, the cheaper Anker SOLIX C300 DC is also worth considering. If you need substantially more battery capacity or want to run higher-powered appliances, I would step up to the C1000 Gen 2.
Verdict: The Anker SOLIX C300X is my portable pick in the range. Its 288Wh battery keeps it compact, while the AC socket gives it more flexibility than the DC-only version without moving into the size and weight of Anker’s larger power stations.
The Anker SOLIX C1000 Gen 2 is the model I would choose if you want significantly more appliance capability than the C300X without moving into the size and weight of a 2kWh power station. It combines a 1,024Wh LiFePO₄ battery, 2,000W continuous AC output and up to 600W of solar input.
That makes it a strong middle-ground option for home backup, campervans, garden buildings and general off-grid use. It has enough inverter power to run a much wider range of household appliances than the smaller C300X while still remaining reasonably easy to move.
Strong Output for a 1kWh Power Station
The standout figure is the 2,000W continuous AC output. That gives the C1000 Gen 2 considerably more headroom than many smaller portable power stations and makes it realistic for a broad range of household equipment.
You should still check the actual running and startup requirements of anything you plan to connect, but this is firmly beyond phones, laptops and lighting. For general backup use, the inverter is unlikely to be the first limitation for most moderate household loads.
Fast Charging
Charging speed is another strength of the C1000 Gen 2. Anker has designed it to recharge very quickly from the mains, which is useful if you need to top it up before a trip or during a period when grid power is available between outages.
That also makes it easier to use regularly rather than treating it purely as an emergency battery that stays stored for most of the year.
600W Solar Input
The C1000 Gen 2 supports up to 600W of solar input, which is a useful amount for a 1,024Wh battery.
In good conditions, a suitably sized solar setup can put a meaningful amount of energy back into the battery during the day. UK weather will obviously reduce real-world output, particularly in winter, but the 600W ceiling gives you much more flexibility than the smaller C300X.
Still Manageable to Move
At around 11.3kg, the C1000 Gen 2 is much heavier than the C300X but still practical to move between rooms, carry into a campervan or take outside when needed.
For me, this is about the upper end of what still feels comfortably portable rather than merely movable. Once you move into the S2000 and larger models, the extra battery capacity starts to come with a much more noticeable weight penalty.
Who Is the Anker SOLIX C1000 Gen 2 Best For?
I think the C1000 Gen 2 makes most sense for general home backup, campervans, garden offices, sheds and users who want higher appliance output without buying a 2kWh unit.
One important limitation is that the Gen 2 is not expandable. If you think you may eventually want 2kWh or more of storage, it may make more sense to buy a larger model from the start rather than expect to add another battery later.
If you want roughly twice the battery capacity while keeping the weight relatively low, the S2000 is the next model I would look at. If higher output and battery expansion matter more than weight and efficiency, the C2000 Gen 2 is the stronger 2kWh alternative.
Verdict: The Anker SOLIX C1000 Gen 2 is a very strong 1kWh option. Its 2,000W output and 600W solar input give it plenty of capability for its size, while the 11.3kg weight keeps it practical for mixed home and portable use.
The Anker SOLIX S2000 is the model I chose for my own setup and my top pick in this guide. It combines roughly 2kWh of LiFePO₄ battery capacity with 1,500W continuous AC output in a particularly compact 16.2kg unit.
That combination won’t suit everyone. The S2000 gives up some inverter power and expandability compared with Anker’s C2000 Gen 2, but in return you get a lighter, more efficient 2kWh power station that is particularly well suited to running moderate loads for long periods.
2kWh Without the Usual Weight
The biggest attraction for me is how much battery capacity Anker has packed into a relatively light unit. At around 16.2kg, the S2000 is noticeably easier to move than many other 2kWh portable power stations.
That matters if you expect to use the same battery in several places. In my case, I wanted something substantial enough for home backup but still realistic to move into a campervan or around the house when needed.
Efficiency Is the Main Selling Point
The S2000 appears to have been designed around efficiency rather than simply chasing the highest possible inverter figure. Anker highlights particularly low idle consumption and strong efficiency when powering relatively modest continuous loads.
That can matter more than headline output when you are running equipment such as a fridge, freezer, broadband router, aquarium equipment, lighting or other devices for many hours. Less energy lost through the inverter means more of the battery capacity is available for the things you actually want to power.
The 1,500W Output Is the Main Limitation
The main compromise is its 1,500W continuous AC output. That is plenty for many everyday appliances and electronics, but it is considerably lower than the 2,400W available from the C2000 Gen 2.
This means the S2000 is not the best choice if you regularly want to run very high-powered appliances or several demanding devices at the same time. Kettles, heaters and cooking appliances in particular can quickly exceed 1,500W.
For my intended use, I’m happier trading some maximum output for lower weight and better long-duration efficiency, but it is an important limitation to understand before buying.
No Expansion Battery
The other significant limitation is that the S2000 is not expandable with an additional battery. You are effectively buying a self-contained 2kWh system.
That is fine if around 2kWh already covers what you need, but buyers who think they may eventually want 4kWh or more should take that into account before choosing it.
Strong Value at the Right Price
Price is another reason I chose the S2000. When it is discounted, it can offer a lot of LiFePO₄ battery capacity for the money, particularly when you consider the relatively low weight and emphasis on efficiency.
I would be less enthusiastic if it were priced close to larger expandable systems, but at strong sale prices the S2000 becomes a very attractive option for anyone who values runtime and portability more than maximum inverter output.
Who Is the Anker SOLIX S2000 Best For?
I think the S2000 makes most sense for home backup, campervans, long-running moderate loads and buyers who want around 2kWh of capacity without moving into a much heavier power station.
It is particularly appealing if your backup priorities are things like refrigeration, broadband, lighting, electronics or aquarium equipment rather than running several high-wattage appliances simultaneously.
What If You Need More Output or Expansion?
If the S2000’s 1,500W output or fixed battery capacity feels restrictive, the Anker SOLIX C2000 Gen 2 is the alternative I would look at. It has a similar 2kWh battery size but increases continuous output to 2,400W and can be expanded to around 4kWh with an additional battery.
The trade-off is extra weight and a less efficiency-focused design, so I wouldn’t automatically choose the C2000 Gen 2 over the S2000. It simply makes more sense for buyers who prioritise higher appliance output and future expansion.
Verdict: The Anker SOLIX S2000 is my top pick because it gives you roughly 2kWh of storage in a relatively light and efficient package at a very competitive sale price. The 1,500W output and lack of battery expansion are real compromises, but for long-running moderate loads and flexible home or campervan backup, I think the balance makes a lot of sense.
The Anker SOLIX F3000 is the model I would choose when home backup matters more than portability. It combines a 3,072Wh LiFePO₄ battery, 3,600W continuous AC output and up to 2,400W of solar input, putting it firmly into serious backup territory.
This is much more than a larger camping battery. The F3000 is designed for longer outages, higher household loads and buyers who want a system that can grow beyond its original 3kWh capacity.
3kWh Gives Much More Breathing Room
The biggest advantage is simple: capacity. At just over 3kWh, the F3000 stores roughly three times as much energy as a typical 1kWh portable power station.
That makes it much better suited to keeping essentials such as fridges, freezers, broadband equipment, lighting, TVs, laptops and other moderate loads running for longer during an outage.
Actual runtime will always depend on what you connect, but this is the point in the Anker range where the battery starts to feel much more like a substantial home-backup system than a general-purpose portable power station.
3,600W Output for Heavier Loads
The F3000 provides 3,600W of continuous AC output, which gives it substantially more headroom than the smaller C1000 Gen 2 or S2000.
That matters if you want to run several appliances at once or use equipment with higher running or startup demands. I would still check the actual wattage of individual appliances, but the F3000 is far less likely to be limited by inverter output during normal household use.
Much Stronger Solar Charging
Solar input is another area where the F3000 takes a major step forward, supporting up to 2,400W of solar input.
That is particularly useful on a battery of this size. Large batteries can take a long time to refill if the solar input ceiling is too low, so the higher limit gives the F3000 much more potential for serious off-grid or emergency use.
As always, UK weather will affect real output heavily, especially in winter, but the higher ceiling means the power station itself is not the main restriction if you build a larger solar setup.
Expandable for Longer Backup
Unlike the S2000, the F3000 is designed to be expanded with additional batteries. That allows total storage to increase well beyond the original 3,072Wh capacity.
This is one of the main reasons to choose it over a large standalone power station. You can start with the base unit and add more storage later if your backup requirements grow.
Portability Is the Main Trade-Off
The downside is weight. At around 41.5kg, the F3000 is not something most people will want to carry regularly.
Anker uses wheels and a pull handle to make it easier to move, but I would still think of it as a movable home-backup battery rather than a genuinely portable power station.
If you expect to move the unit between the house, campervan and garden frequently, the S2000 is much easier to live with. The F3000 makes more sense when the unit will mostly stay in one place.
Who Is the Anker SOLIX F3000 Best For?
I think the F3000 makes most sense for serious home backup, longer outages, higher-powered appliances, large solar setups and buyers who want expandable battery storage.
It is probably excessive for occasional camping or light emergency use, but if your priority is keeping several household essentials running for extended periods, the extra capacity and inverter power become much more valuable.
If you want something easier to move and do not need 3,600W of output, I would look at the S2000 instead. If you want even more expansion and higher household output, the larger F3800 is the next model worth considering.
Verdict: The Anker SOLIX F3000 is the strongest choice in this guide for serious home backup. Its 3,072Wh battery, 3,600W output, strong solar input and expandable capacity make it far more capable than the smaller SOLIX models, but the 41.5kg weight means that extra capability only makes sense if you genuinely need it.
Anker S-Series vs C-Series vs F-Series – What’s the Difference?
Anker’s naming can be confusing because the different SOLIX ranges are not simply a progression from small to large.
The C-Series is the mainstream portable power station range, covering compact models such as the C300X through to the C1000 Gen 2 and C2000 Gen 2. These models generally prioritise a balance of portability, charging speed and appliance output.
The newer S2000 takes a slightly different approach. Rather than chasing the highest inverter output, it focuses more on efficiency, compact size, low weight and long battery life. That makes it particularly interesting for running moderate loads over long periods.
The F-Series moves much more clearly into serious home-backup territory. Models such as the F3000 offer much larger battery capacity, higher AC output, stronger solar input and expandable storage. The F3000, for example, provides 3,072Wh of capacity, 3,600W output and expansion from around 3kWh to 12kWh.
For most buyers, I would choose based on how the power station will actually be used rather than the letter in the model name. The C-Series suits general portable power, the S2000 is particularly appealing for efficient 2kWh backup, and the F-Series makes more sense when larger-scale home backup is the priority.
What About the Anker SOLIX C2000 Gen 2?
The C2000 Gen 2 is the main alternative I would consider if you like the S2000’s roughly 2kWh battery size but need more appliance power or future expansion.
It has a 2,048Wh battery, 2,400W continuous output and up to 800W solar input. It can also connect to the BP2000 Gen 2 expansion battery, giving it an advantage over the S2000 if you expect your storage needs to grow.
The trade-off is that it is heavier and less focused on low-load efficiency. That is why I still prefer the S2000 for my own use, where long runtime, lower weight and moderate household loads matter more than being able to run several very high-powered appliances at once.
If your priority is higher AC output and expandability, I would choose the C2000 Gen 2 instead.
Which Anker Size Do You Actually Need?
The easiest way to choose between Anker portable power stations is to separate battery capacity from inverter output.
Battery capacity, measured in watt-hours (Wh), largely determines how long your equipment can run. AC output, measured in watts (W), determines how much power the unit can supply at once.
For phones, laptops, cameras and lightweight camping use, the C300X may be all you need.
The C1000 Gen 2 is the best fit if you want a compact 1kWh power station with strong appliance output. It provides 1,024Wh capacity and 2,000W continuous AC output.
The S2000 makes more sense when you want roughly twice the battery capacity while keeping weight and efficiency under control.
For serious home backup, the F3000 moves into a different class entirely, with 3,072Wh capacity, 3,600W output and expandable storage.
How Much Does Solar Input Matter?
Solar input matters more as battery size increases, because a large battery can take a very long time to recharge if the power station only accepts a small amount of solar power.
- C300X: up to 100W
- C1000 Gen 2: up to 600W
- S2000: up to 400W
- F3000: up to 2,400W
The F3000 is the standout here. Its dual solar inputs allow up to 2,400W of solar charging, which is much better suited to a large 3kWh battery and serious off-grid use.
As always, maximum solar input only tells you how much the power station can accept. A 2,400W-rated setup will not continuously produce 2,400W throughout a typical UK day, particularly in winter.
Anker Portable Power Station or Solar Generator?
The terminology is simpler than it first appears. The Anker SOLIX unit itself is a portable power station: it contains the battery, inverter, charging electronics and output sockets.
When you connect compatible solar panels, the complete setup is commonly described as a solar generator.
You therefore do not need solar panels to use an Anker power station. It can be charged from the mains and kept ready for camping, campervan trips or emergency backup. Solar simply gives you another way to recharge it when mains electricity is unavailable.
Are Anker Solar Panels Worth Buying?
Anker sells its own portable solar panels designed to work with the SOLIX range, and these are usually the simplest option if you want a straightforward plug-and-play setup.
However, you are not necessarily restricted to Anker-branded panels. Compatible third-party solar panels can also work, provided their voltage, current, connector type and total input stay within the limits of the power station.
Before connecting any panel, check:
- open-circuit voltage (Voc)
- operating voltage
- maximum current
- connector type
- maximum solar input
Do not choose a solar panel solely because its advertised wattage looks suitable. Electrical compatibility matters just as much as the headline wattage.
Final Thoughts
For my own use, the Anker SOLIX S2000 is the model I chose because it offers roughly 2kWh of battery capacity in a relatively light, efficient package at a very competitive sale price.
The main compromises are its 1,500W continuous output and lack of battery expansion, so it will not suit everyone. If you want higher appliance output or future expansion, the C2000 Gen 2 is the stronger alternative.
The C300X is the better choice for genuinely lightweight use, while the C1000 Gen 2 is a strong middle-ground option if you want a compact 1kWh system with 2,000W output.
For serious home backup, the F3000 is the clear step up. Its 3,072Wh battery, 3,600W output, 2,400W solar input and expandable capacity make it far more suitable for longer outages and larger solar setups.
As with EcoFlow, Jackery and Bluetti, the right Anker is not necessarily the biggest or newest model. The best choice is the one whose battery capacity, inverter output, solar input, weight and expandability best match how you will actually use it.
