Review of Powkey 200Watt Portable Power Bank

I have been using the powkey 200 watt power bank for a year, so far it holds up good.  I use it when I go

camping, charging with a solar panel.  It is designed for devices that don’t require much power such as

cellphones, tablets, laptop computers, cameras, drones, etc.  It is not powerful enough to run cpap machines, 

refrigerators for a decent amount of time.  For those higher energy devices, you would need a minimum

of a 500 Watt Device, in my opinion.

When looking for a portable power station, these are the most desirable features:

1. Pure Sine Wave Inverter
2. Has MPPT Charge Controller (Maximum Power Point Tracking)
3. Able to perform pass through charging, meaning you can charge the unit and use the unit at the same time.
4. Has a regulated 12V output, for charging of some items like phones, tablets, etc it is not a big deal, however some appliances like
a refrigerator might not work without a regulated 12v output.
