Anker SOLIX C300 DC
A 0.288 kWh pocket-size power box with 300W output, 140W two-way fast charging and backup for small essentials in a power cut. Handy for camping, travel and short outages, but it cannot feed your home wiring, so it can't cut energy bills.
UK rules check

- LFP battery in a small, portable box
- 7 ports including dual 140W USB-C

Common questions
Is the C300 DC a plug-in home battery?
No. It is a portable power box: it stores energy and runs small appliances plugged into its own sockets. It cannot feed power into your home wiring (see our guide on the difference).
