OutdoorGearLab's best value and Popular Science's budget pick: about 1 kWh that recharges from the wall in under an hour, with six AC outlets and 140 W USB-C. Its fan gets loud near full load, and unlike the first generation it can't add expansion batteries and has no built-in light.
Top complaints
- Loud fan at high load
OutdoorGearLab calls the fan frustratingly loud near maximum wattage, a carry-over from the first generation.
- No expansion and no light
OutdoorGearLab notes it no longer supports expansion batteries and the built-in light was removed.
- Not for RVs or large appliances
Popular Science's con is that it isn't suited to RVs or large appliances. Battery life gets 31 negative mentions on Amazon against 93 positive.
What owners love
- Very fast recharge
OutdoorGearLab measured 56 minutes (49 in ultrafast mode), about 1,097 Wh/hr. Popular Science saw about 50 minutes. Amazon owners frequently praise the charging speed.

- Plenty of outlets and a useful app
Six AC outlets, two USB-C, two USB-A and a car outlet. The app lets you set charge and discharge limits (OutdoorGearLab). Popular Science notes a 10 ms UPS switchover.
