When the Goal Zero pooped out I bought the above tiny battery/ solar thingie. It was slower than I was hoping for. Could only charge 1 item a day. The batteries and the Kindle and the lights were lined up to be charged.
So I set up the left over panels from the Goal Zero package. That helped by adding one more charge spot. These are very slow, also. The poor panels have been in hail storms and dust storms. But, they still work. Kinda.
The phone’s battery is getting weak, so it has an extra battery attached most of the time. Getting all of these items charged is hard. Thanks to a friend I just unwrapped and set up the Jackery 100 watt solar panel.
Very fast. Only one USB port. But fast. And On sunny days all of the solar panels are out and charging! By tonight I will have 2 full batteries , fully charged phone, fully charged light and a full Kindle.
