This Anker station suits portable backup power for electronics, not whole-home use, given its compact 288Wh LiFePO4 pack, fast USB-C recharging and solar input restricted to Anker's own panels.

Overview
The Anker SOLIX C300 DC is a 288Wh LiFePO4 portable power station rated for 300W continuous output, built for campers, remote workers and anyone who wants backup power for phones, laptops and small appliances without a gas generator.
Anker positions this as a compact alternative to bulkier power stations, claiming a 30% smaller footprint than comparable units. It ships without a wall charger, so budget for an 18W or higher USB-C charger to activate and recharge it out of the box. Solar charging works only with Anker's own 100W or 60W panels; older SOLIX PS30, PS200 and PS400 panels are explicitly not compatible.
- 288Wh LiFePO4 battery pack
- 300W continuous output
- Dual 140W USB-C fast recharging
- Compatible with Anker 60W/100W solar panels
Who it's for
Campers, RV owners and anyone assembling a small home backup kit for phones, laptops, routers and similar electronics will get the most use from this. It is not sized for power tools, large appliances or extended off-grid living, where a higher-wattage station would be needed.
Pros and cons
- Two-way 140W USB-C ports charge fast in either direction
- LiFePO4 battery backed by a 3-year guarantee
- Seven output ports cover phones through a 120W car socket
- About 30% smaller than similar-capacity stations, Anker says
- No wall charger included, so activation needs one on hand
- Only works with Anker's own 100W or 60W solar panels
- 288Wh capacity limits it to small electronics, not appliances
Performance notes
Two-way 140W USB-C ports handle charging in and fast recharging out, with Anker claiming an 80 percent refill in about an hour via the dual PD 3.1 input. LiFePO4 cell chemistry and built-in temperature control back the 3-year guarantee, and seven output ports (two USB-C up to 140W, one at 100W, one at 15W, two USB-A, one 120W car socket) spread the load across several devices from one charge.
