At $0.3331/Wh, the HELIOS 3600 ranks among the best value options available. 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 3600Wh of storage, this station can run a laptop for approximately 47.1 hours, keep a mini-fridge running for 38.3 hours, or charge a smartphone around 204 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.
Bottom line: If you need 3600Wh of portable power and the current price of $1199 fits your budget, this is a solid choice. Check the price history chart above to confirm you are buying at or near the historical low.
With 7200W of AC output and 3600Wh capacity, it can run most household appliances under 7200W. Common uses: laptop (47.1h), LED lights (24h+), WiFi router (12h+), mini fridge (38.3h), CPAP machine (102h). 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 excellent value - well below the market average. 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.
