Bests & Worsts Reviews from Amazon

This is a very good product.. IF you know how to use it.. by using it, i dont mean "plug it into your iphone and expect 0% to 100% in couple hours".. you MUST buy a usb power meter tester! this is the only way you will test your charging rate! and make sure charge rate increases after a cloud passes.. yea you can plug it in to your iphone and it will show charging, but when the cloud passes, you must look into your usb power meter if the charging rate increases again, if it does not, this product is useless for you but you cant blame it.. i use a EasyAcc 26,000 mah battery pack with it, the Solar Charger has 2 outputs that you can connect to a EasyAcc battery pack into its both inputs.. so; with this battery pack; if a cloud passes, obviously the charge rate decreases to about .15amps depending on weather conditions.. charge rate should automatically increase after a cloud passes and the sun shine is out.. my iPhone 6s doesn't do that, when the sun is out i get .95amps, thats very good, as soon as a cloud passes, i get .15ish amps, then it stays like that for the rest of the day till i manually unplug and plug the iPhone 6s in it.. the EasyAcc automatically allows charge rate to increase after a cloud passes.. I thought i had figured it out.. its fun to see the charge rate as you are charging your "anything" using the sun.. but it is not comfortable to plug the USB Power Meter Tester into the back of the panels, hold it at the same time and watch the charge rate.. I bought USB extension cables to plug them into the Solar Charger and than plug the USB Power Meter.. BIG MISTAKE!!! the cables only allow .46amps MAX, they slow down the charge current.. make sure your cables are good, mine aren't.. but when i plug the USB Power Meter directly into the Solar Charger, i get .96amps into my iPhone 6s (10am sunlight in New York).. test it out before you use it.. all cables, phones, battery packs are different.. research, research and again, the EasyAcc 26,000mah power bank works amazing with this unit, and so as the RavPower 26,800 mah I got.. its only down hill is that its got only 1 input to charge the device, not 2 inputs like the EasyAcc.. I also have a Mophie 12,000 mah battery pack, this one will charge as the sun is looking at it, but once the clouds block the sun, the charge current drops, and will stay like that very low till the night.. RavPower and EasyAcc automatically increase charge current as the sun begins to shine.. Just because you see a charging icon on your iphone does not mean you are charging it at a good rate.. same for battery packs.. test your stuff and this Solar Device is for you! Kinda sucks that no one warns about this issue, i learned the hard way.. I could of not known this product and gave a 1 star review? many negative reviews are by the people who don't know how to use this product and did not test it.. giving this a 1 star when its a good product that id give 10 stars if i could!
