In this guide
The Anker SOLIX S2000 has arrived at CEN: 2kWh of LFP capacity rated for 10,000 charge cycles, recharged six different ways including 400W of solar, in a body around 30% smaller and 25% lighter than the average 2kWh station. £649, in stock now.
The number that actually matters
Capacity sells power stations; cycle life decides whether you're still using one in a decade. The S2000 uses high-capacity 314Ah lithium iron phosphate cells rated to 10,000 cycles — Anker quotes a 15-year design lifespan under normal daily use before meaningful capacity loss. Compared with the lithium packs that dominated this category a few years ago, that's a different class of longevity.
2kWh, and what that gets you
Two kilowatt-hours is the sweet spot for serious but portable off-grid power: a compressor fridge, lights, laptops, drone and camera batteries through a long weekend, or around 24 hours of backup for household essentials when the power goes out. Our capacity guide walks through doing the sums for your own kit.
Smaller, lighter, faster to fill
The engineering story here is density. Anker has packed 2kWh into a case meaningfully smaller and lighter than the category average, which matters enormously for van conversions and boot space. It recharges from empty in roughly two hours on mains, and takes up to 400W of solar for genuinely self-sufficient stays. A very low idle draw means it holds its charge while sitting unused between trips, rather than quietly emptying itself in the garage.
Our take
This is the size of power station most people should buy if they're buying once: big enough for real off-grid use and home backup, small enough to actually carry, with a cycle rating that justifies the outlay. It sits above the C1000 in our Anker SOLIX range, and expansion batteries are available if your needs grow. Tell us what you need to run and we'll check the numbers with you before you commit.
Frequently asked questions
What can the S2000 actually run?
2kWh covers a fridge, lights, laptops and camera kit for days of camping, or keeps essentials running through a power cut. Check your most demanding appliance's wattage against the station's output before relying on it.
What does a 10,000-cycle battery mean in practice?
Charge cycles are the honest measure of a power station's life. At 10,000 cycles of LFP chemistry, Anker rates the S2000 for around a 15-year design lifespan under normal daily use — far beyond older lithium packs.
Can I charge it from solar?
Yes — solar is one of six recharge routes, at up to 400W, alongside mains and vehicle charging. It reaches a full charge from mains in about two hours.
Is it worth the size saving?
If it goes in a van or car, yes. It's around 30% smaller and 25% lighter than the average 2kWh station, which is the difference between kit you take and kit you leave at home.
