Power stations & solar panels
Capacity, output and charging from the wall, the car or solar panels.
What to check before you buy
- Capacity in watt-hours and continuous output in watts for the devices you plan to run.
- Battery type and the number of charge cycles the manufacturer rates it for.
- Charging time from a wall socket, a car and solar panels, plus the solar input limit and connector type.
- Weight, the sockets and ports it has, and the manufacturer’s instructions on ventilation and storage.

LiFePO4 vs NMC Batteries in Portable Power Stations
LiFePO4 (LFP) power stations are heavier for the same watt-hours but are usually rated for many more charge cycles and are generally regarded as more thermally stable. NMC units are lighter. Read the chemistry, cycle rating, weight and UL 2743 listing on the spec sheet.
Portable Power Station vs Gas Generator for Home Power Outages
A battery power station suits apartments, short outages and small loads because it makes no exhaust. A gas generator suits multi-day outages and big loads, but only outdoors. Many homes end up using both.
How Big a Portable Power Station Do You Need for a Power Outage?
Add up the watts you need at the same time, then the watt-hours you need for the whole outage. A fridge, router, lights and phones for one day come to roughly 1.6 kWh, so look at stations rated near 2,000 Wh.
