At $0.7303/Wh, the Generic 178.0Wh 4200W is average value — consider larger capacity models for better $/Wh. The key question is whether this capacity fits your actual needs. A station you rarely use is wasted money regardless of $/Wh — use our runtime calculator to verify it covers your devices.
With 178Wh of storage, this station can run a laptop for approximately 2.3 hours, keep a mini-fridge running for 1.9 hours, or charge a smartphone around 10 times. Actual runtime depends on the efficiency of your specific devices and the ambient temperature.
The battery chemistry is standard lithium-ion, which lasts 300-800 cycles - typically 2-4 years with regular use. For most buyers planning regular use (weekly or more), this is an important consideration — see our full LiFePO4 vs Li-ion comparison.

With 4200W of AC output and 178Wh capacity, it can run most household appliances under 4200W. Common uses: laptop (2.3h), LED lights (24h+), WiFi router (12h+), mini fridge (1.9h), CPAP machine (5h). It cannot run high-wattage appliances like electric ovens, space heaters, or central AC.
Charge time is typically 1-3 hours from a wall outlet. You can also recharge via solar panels or your car's 12V outlet, though these methods are slower than wall charging.
this is above average - consider a larger capacity model for better $/Wh. The average price per Wh across all stations we track is around $0.55/Wh. Use our best $/Wh rankings to compare with all available options.
