Anker SOLIX C1000 - Introduction
For most of us, an electric hook-up (EHU) remains the default expectation when arriving on a pitch. Plug in, power up, done. But not every trip goes that way. Certified Locations (CL) sites, farm stopovers, and remote touring spots often lack hook-up facilities entirely, and even standard site hook-ups are typically limited to 10A or 16A - enough to run the essentials but not exactly generous if you want to use multiple appliances at once.
That gap is exactly where the Anker SOLIX C1000 sits. It is a 1056Wh lithium iron phosphate (LiFePO4) portable power station capable of delivering 1800W continuously, with brief surges up to 2400W to handle the initial start-up demands of appliances like coffee machines and kettles. It charges fully in under an hour from a mains socket, accepts up to 600W of solar input, and can be controlled and monitored remotely through the Anker app.
At 12.9kg, it is not something you carry lightly, but it is compact for the amount of power it offers and is shaped to slot neatly into a caravan storage space or sit flat on the floor. Whether you are extending your independence on site or simply reducing your reliance on EHU, the C1000 is one of the more capable options in this class.
Key Features
The headline figure is the 1056Wh LiFePO4 battery. LiFePO4 chemistry is the preferred choice for portable power stations because it handles heat better than standard lithium-ion, sustains more charge cycles over its lifetime (rated at 3,000 cycles), and is more thermally stable. Anker rates the battery for a 10-year lifespan under normal use conditions, which makes it a realistic long-term investment rather than a disposable gadget.
The SurgePad technology handles the 1800W continuous output and allows brief peaks up to 2400W. In practice, this means the C1000 can start appliances that draw a short high-power burst on startup - a coffee machine, a small electric drill, a fan - without tripping out. It covers the vast majority of portable appliances you would reasonably bring on a caravanning trip.
Charging speed is a genuine standout. Using the Anker app to enable UltraFast mode, the C1000 recharges from empty to full in around 58 to 65 minutes via a standard mains socket. This matters when you have limited access to power - either from an EHU on site or from a socket at home before you depart. Critically, the app also lets you reduce the input wattage down to 200W if you want to trickle-charge the unit from a hook-up without hogging your entire site allowance.
Solar charging supports up to 600W input via the XT60 connector, and Anker claims a full solar recharge in approximately 1.8 hours in ideal conditions. Real-world solar output will always vary depending on weather, panel angle, and time of year, but even in partially overcast UK conditions a decent solar panel setup will meaningfully top the unit up across a day on site.
The 11 output ports include 6 UK AC sockets (230V), 2 USB-A, 2 USB-C (one rated at 100W for laptops), and a 12V car-style socket. The layout is well thought through, and the inclusion of a 12V output is handy for running DC accessories like compressor fridges and electric blankets. A built-in LED light bar with three brightness settings and an SOS mode provides a useful camp light without consuming a socket.
Connectivity is handled via Bluetooth and Wi-Fi through the Anker app, which gives you real-time power draw figures, remaining runtime estimates, input speed control, and the ability to toggle individual outputs on and off remotely. The flat top surface doubles as a useful shelf for phones and tablets while charging.
For caravanners who need more capacity, Anker offers an optional expansion battery that adds a further 1056Wh, bringing the total to 2112Wh. This connects via a single cable and roughly doubles your available runtime across all outputs.
Pros and Cons
Pros
1056Wh LiFePO4 battery with 3,000-cycle lifespan and 10-year rated durability
Full charge in under an hour from mains - fast enough to top up between pitches or before departure
1800W continuous output (2400W surge) handles most caravan appliances comfortably
Up to 600W solar input with 1.8-hour solar recharge capability for genuine off-grid use
App-controlled charging speed: dial input down to 200W to avoid overloading a site EHU
11 output ports including 6 AC sockets, USB-C 100W, 12V car socket, and LED light bar
Compact for the capacity - 15% smaller than comparable 1kWh units according to Anker
Expandable to 2112Wh with the optional companion battery
Low standby drain - leaves the unit on without significant battery loss
UPS function (under 20ms switchover) protects sensitive equipment during power transitions
Cons
12.9kg is a meaningful payload commitment - worth factoring into your outfit's weight budget
Fan noise at high loads and during fast charging is noticeable in an enclosed caravan space
Original model cannot simultaneously charge from solar and AC - one input at a time
No DC 5521 barrel ports, which limits compatibility with some 12V accessories
UltraFast charging mode requires the Anker app and a smartphone to enable
High internal overhead means efficiency at very low loads (under 10W) is not optimal
Performance
The 1056Wh capacity sits in a practical range for caravanning use. It is enough to run an electric cool box for 24-36 hours, charge a laptop a dozen or more times, power LED lighting throughout the evening, and run a portable projector across several long nights. It will not run a full-size electric heater for any meaningful duration - those draw 1000-2000W continuously and would flatten the battery in under an hour - but that is not what this class of product is designed for.
For off-grid pitches, the combination of solar recharging and the C1000's output makes a credible standalone power setup. A 200-400W solar panel array connected via the XT60 input will meaningfully replenish the battery through a reasonable day, and you can supplement with mains charging whenever a hook-up becomes available.
On pitches with EHU access, the C1000 pairs well with your hook-up rather than replacing it. You can charge the unit overnight at a reduced input rate (set via the app) without affecting the caravan's own power draw. That way, you have a fully charged reserve available for appliances that briefly exceed your site's amperage allowance. If you are not yet using a quality hook-up cable, our review of the Semloh 25m Caravan Electrical Hook-Up Cable is worth reading before charging any high-capacity device from a site pedestal.
The fast charging capability is genuinely useful in practice. If you forget to charge before a trip, or you get an unexpected opportunity to plug in briefly at a service stop, the ability to go from nearly flat to full in under an hour removes a lot of the anxiety that comes with off-grid touring.
One real-world consideration worth flagging for caravan use is the fan noise. When the unit is charging rapidly or running heavy loads, the internal cooling fan is clearly audible. In a living space the size of a caravan, particularly overnight, this matters. The fan runs quietly at lower output levels - powering a laptop or charging phones produces minimal noise - but if you are fast-charging the unit from a hook-up while inside the van, you will hear it. This is not unusual in this class of product, but it is worth being aware of before positioning the unit.

Why It's Recommended
The Anker SOLIX C1000 earns its place in this guide because it addresses a genuine gap in the caravanning setup: meaningful off-grid power in a unit that is actually portable. At 12.9kg with two sturdy handles, it can be transferred between home, car boot, and caravan without requiring a second person, and its flat, compact profile means it fits alongside other gear rather than dominating the space around it.
The combination of fast mains charging and 600W solar input gives it flexibility across different touring styles. Weekend caravanners with occasional EHU access can charge it at home and top it up on site. Those who regularly use non-EHU pitches can pair it with a solar panel setup and run largely on free energy throughout a stay. The app control, while requiring a smartphone, adds genuine practical value by letting you dial the charge rate to suit your hook-up allowance and monitor your exact remaining runtime.
LiFePO4 chemistry is the right choice at this price point. It lasts significantly longer than standard lithium-ion, handles the temperature variations of outdoor storage more capably, and carries a better safety profile. The 3,000-cycle rating means the battery remains viable for a decade of regular use.
There are limitations. The weight is a real consideration for anyone managing a tight payload. The fan noise at full load is a genuine nuisance in close quarters. And the original model's inability to accept solar and mains input simultaneously is a minor frustration when both are available. But as a standalone off-grid power source, or a capable supplement to an EHU setup, the C1000 is hard to fault for the money at its frequently discounted price.
