Charged my 300Wh power station from 25% to 97% in one day. I just move it 3 times and it works like a charm. Outstanding quality of work. No stupid cloth handles that will tear in a year or two. And the material on the outside and back feels very durable. When locked, there's enough room for an iPad, and I chose USB-C charging because you need to use the solar panel as soon as possible. If it can pull the full 45W, it will charge your devices much faster than any USB-A port. I use it with my golab 300w and use a normal plug without an adapter. The cord is about 3 feet long, which allows me to place the solar panel on top of the picnic table and the power station safely underneath. Good product.
