I would recommend a 20usb charging station. Because, my is working fine since I last time use it either to charge all my power banks and accessories or using it on my battery station. Plus I got my 20usb charging station off of the Walmart website & don’t remember how much it cost. But it’s the low power one that is rated for either 80Watts or 100watts. I didn’t get the powerful one to save a little bit of money. In fact I would recommend on getting 2 20usbs charging station vs these and would have 40usbs total in a different way.
