Perfect for our camping needs. This gives us the extra power to charge up phones and other devices while out hiking and camping. Small enough to put in a backpack if needed.

Good product for the price.

Works great. And full sun changes quick. When I am at work set up in the bed of my truck. Wheel bumps angle it to the sun.

I like the size of this power supply. It stores enough power to operate my cpap machine for 1 to 2 days (I've used it) and easily recharges with the solar panel. I plan to use it while camping. Overall, q great choice for me.

Perfect for keepin my electronics running while camping. The solar panel charges the battery faster than plugging into an outlet charger. The battery pack is small, but that is good for my use. I'm glad I purchased this.

not know the type of usb it has

Small and Compact Power Battery Storage

Great for charging phones during power outage or hurricane

This is good for reliable charging while traveling or camping. The solar panels are adequate but also slow typlical of solar.

The connection to the battery box is a very flimsy DC adapter to USB C and broke off the first time I tried to charge it. They need a standard durable DC plug connector to charge the battery.
