Anker SOLIX C1000 vs BLUETTI Elite 300
Technical comparison · Home backup
Two home batteries with no-break output, but different sizes: one just over 1 kWh that one person can carry, one at 3 kWh that usually stays where it is installed. What decides it is how long, and with what load, a blackout has to be covered.

The differences that matter
- 1.06 kWh vs 3.01 kWh → at a 200 W load, in theory about five hours against fifteen.
- 12.9 kg vs 26.3 kg → the first moves from room to room by hand; the second is best left in one place.
- 2,400 W vs 4,800 W peak → the second has more headroom when a motor or compressor starts.
- 5 years vs 2 years of warranty → on both, the warranty runs out before the cycle count does, so the first is covered for longer even though it declares fewer cycles.

Which one to choose
Choose Anker SOLIX C1000 if…
you want something to keep in a cupboard and carry around: router, laptop and a few lights during an outage, or a weekend away from a socket. The trade-off is the reserve: at full load it lasts about half an hour. In return the warranty runs longer.
Choose BLUETTI Elite 300 if…
you want several things running together in an outage, such as a kettle and a router, or a load with a heavy start-up like a pump or compressor. You pay in weight, since it is awkward to move, and in a shorter warranty. At full load it lasts about an hour and a quarter, so the extra reserve pays off with moderate loads.
