AFERIY Portable Power Station 3600W 3840Wh vs Anker SOLIX F3800 Portable Power Station

Our Verdict

These two share the same 3840Wh base capacity, but the AFERIY P310 costs roughly half the price of the Anker SOLIX F3800 (£1,239 vs £2,699) — you're paying the Anker premium for much higher continuous output (6000W vs 3600W) and a far larger expansion ceiling (26.9kWh vs 11.52kWh). For most UK home-backup users, the AFERIY covers typical household needs at a fraction of the cost; the Anker only earns its price if you specifically need to run very high-draw appliances simultaneously, direct EV/RV charging, or plan to scale toward whole-home backup.

Which one should you buy?

Typical home backup (fridge, lighting, routers, a few appliances): the AFERIY's 3600W output and 3840Wh capacity is genuinely sufficient, and at less than half the price it's the better value pick for most UK households.

Heavy simultaneous loads or workshop use: the F3800's 6000W output and 7200W-equivalent surge headroom handles things the AFERIY's 3600W ceiling can't — running a table saw and a compressor at once, for example — which matters more to tradespeople and off-grid workshops than campers.

Long-term scalability: if you want a path toward multi-day or whole-home backup, the Anker's 26.9kWh expansion ceiling (via up to 6 battery packs) is in a different league than the AFERIY's 11.52kWh cap — worth the premium only if you're planning that scale from the start.

EV/RV charging: the F3800 supports direct EV charging and RV power inlets natively; the AFERIY doesn't offer this as a built-in feature, so RV/EV owners lean Anker regardless of price.
