It the most cost effective option on the market right now – parameters are not overstated: 2 USB output ports able to deliver up to 3A of current (combined) so its able to charge any smartphone out there. It doesn’t even require full sun to charge(performance is reduced of course). The same product is sold on amazon and elsewhere under Anker 20W and Anker 21W panel if you want to search for more reviews. It’s now even cheaper than in preorder one year ago…
