At $0.5277/Wh, the Generic Apex 300 & B300K offers good value for its capacity range. 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 5529.6Wh of storage, this station can run a laptop for approximately 72.3 hours, keep a mini-fridge running for 58.8 hours, or charge a smartphone around 313 times. Actual runtime depends on the efficiency of your specific devices and the ambient temperature.
The LiFePO4 battery chemistry is LiFePO4 (Lithium Iron Phosphate), which lasts 2,000-4,000 cycles - roughly 10-20 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 3840W of AC output and 5529.6Wh capacity, it can run most household appliances under 3840W. Common uses: laptop (72.3h), LED lights (24h+), WiFi router (12h+), mini fridge (58.8h), CPAP machine (156.7h). It cannot run high-wattage appliances like electric ovens, space heaters, or central AC.
