A part of the review has been auto-translated.
During my first test, even near the autumn sunset, it produces 18 volts, which was enough for ~ 10 watts of charging energy with the right car USB charger.
Good dashboard. I've been serialized on the little ones, two on two. And I called in serial numbers with the others... charging the car battery in no time... I'm buying another one...
thank you banggood works very well
I like this product. It generates 3.7V even in low sunlight. Thanks
Excellent goods, reached quickly enough, plus quarantine:) Everything works, after checking with batteries I will add a review! The packaging desires the best, a little jammed the edge of the panel and a bend in the middle while everything works.
Great product, quality and good price!!
These look like they are made well however, there is NO WAY they are 100 watts. I get 10-13 watts in full California sun.
nice solar
The panel is about 20W and not 100W but otherwise ok. I installed it in my station wagon from the side to the trunk, and I'm measured that on a sunny day it's capable of recharging the flashlight without much trouble. There is a reverse diode in the panel module to avoid battery discharge overnight.
D I enter normal, OK. The carrier complained that it had called me before and I didn't answer, wanted me to pick up the order almost halfway through the trip!
