Review on Portable Solar Charger: BigBlue 28W Solar Panel with Digital Ammeter, 2USB (5V/4A) - Camping, iPhone, Huawei, LG, Google Pixel by Roxanne Medina

I think this is a unique product on Revain, I usually saw some promotions including a solar charger along with a separate ammeter, or you may even have to look at many sellers' sites and see what the best price may be. A good ammeter is priced between $10-$15, plus $40-$55 for a solar charger. With this product you get and at a lower price and it works great. Wherever I go (I love sightseeing and I love photography), I can always charge my devices; I charge my iPhone 7 and my digital camera without any problems, so thanks to the BigBlue solar charger my phone never runs out and I can take photos for days. In addition to being useful, it is very simple and with an elegant design. For good performance, place it on the ground so that the sun's rays fall perpendicularly on the panels, with no trees or shade in between. Connect the device by cable only AFTER opening the four covers and charging will start immediately (you can see the charger has power by checking the red LED indicator). It has 2 USB ports (I see the old version had 3), but this new version has a zip pocket, which is much safer and more convenient when hanging from your backpack with a solar charger. Just put your device inside, zip up and let it charge! Highly recommended for those who love outdoor activities, a durable, waterproof and reliable product at such an affordable price. and backed by a guarantee!
