What it can run, and for how long
A power station is a battery with an inverter: it stores energy as watt-hours (Wh) and delivers it as AC watts (W). The FlashFish E103 Portable Power Station stores 179 Wh, of which about 152 Wh reaches your appliances after losses, and its inverter limits the load to 300 W at a time.

Recharging
Recharge time depends on the source. Solar numbers below are our calculation for the panel wattage shown, assuming 75% real-world output and the approximate annual-average peak sun hours for each region; winter and cloud cover cut them sharply.
| Panel total | Basis | Florida and the Gulf Coast | Texas | California |
|---|---|---|---|---|
| 100 W | — | 0.5 sunny days | 0.5 sunny days | 0.4 sunny days |
| 200 W | — | 0.2 sunny days | 0.2 sunny days | 0.2 sunny days |
| 400 W | — | 0.1 sunny days | 0.1 sunny days | 0.1 sunny days |
See the solar recharge calculator for your own panel size and sun hours.
Connecting it to a home
You can plug appliances straight into the unit's outlets. Powering a home's circuits is different: it needs a properly rated transfer switch or the maker's home-integration hardware, installed by a licensed electrician.
If you plan to connect it to the house, compare it with the equipment in our transfer switch and hookup library and read the whole-house guide.
