In-depth review
What it's like to own
ALLWEI's 300 W unit is as simple as power stations get: one AC outlet, a 60 W USB-C port, DC barrel jacks and a car socket, wrapped around a 256 Wh LiFePO4 battery rated for 3,000 cycles.
The trade-off for the price is charging speed: 3.5 to 4 hours from the wall and 4 to 5 hours from a 100 W panel. There's no app and no UPS mode.
Owners report running a CPAP without heat for about 20 hours over three nights, and one mountain owner bought three to ride out wind-related shutoffs. A few note the battery gauge can drop suddenly near empty.
