Love this device!! I've used several solar panels in the past, and though this is the biggest of them all, its the least klunky and easiest to pack and use. Solar panels typically last me a year, sometimes two. I abuse my items hard in the back woods, so price, weight and durability mean a lot to me. This meets and exceeds my standards so far! Fast charging in good light, being dumped in a lake proof, survived a few drags and drops. I like the 2 ports so I can charge my power bank and device simultaneously. This thing is so damn simple to use. Point, plug and enjoy my coffee. I really like this and will be buying another to gift to my friends at christmas time for next year! Pro's: grommets make hanging and pointing in the direction of direct sunlight easy. Large panels for big charging power. Durable. Very Lightweight for the size. Pouch holds my cables well. Folds well in any direction for easy placement. Con's: one velcro closure on large pouch makes the cables fall out on occasion. Makes me want to bring more chargeable items. Will buy another.
I couldn't believe how fast this unit recharged my phone/gps satellite tracking unit and anything else I plugged into it. The price was superior to any other solar charging panels I looked at. The unit itself is very durable. Watched many youtube reviews and this Anker product has them all beat in speed of charging as well as cost. I've used it extensively on my backcountry hunting/backpacking trips. I also keep it in my winter survival kit when out on the land, on the boat, hunting etc..Highly recommend! Great purchase.
Purchased this for a 6 week camping trip to help charge 2 x 10,000mah batteries for an iphone 8s and a Pixel 2. I wasn't expecting it to keep up with our usage, but it did a fantastic job! Placing it on the top of our tent through the midday sun, or angled towards the sun in the morning/afternoon making sure to always be topping up either of the two backup batteries. Our phone usage was medium/heavy with google maps, photo uploads and Pokemon Go. Both phones would receive a top up charge twice a day from the backup batteries, with those charged throughout the day from the panel.
I took it on a week long solo hiking trip in the backcountry and am absolutely happy with the performance and product. It charged my phone and a small power bank enough at lunchtimes to keep going through the day and top up my GPS watch. I did figure out that if I was trying to charge my phone in partial light, the on/off (shadows passing from clouds etc) would drain my phone's battery but this didn't happen with the power bank. I often had it strapped to my backpack while out hiking and that worked great. No issues with time to charge (close to what it would take plugged into the wall). Only thing I didn't like is if it was hanging from the grommets, the pocket is open to the ground so stuff falls out. The velcro is too short to hold anything in so I'm going to add velcro the whole way like it is on the putter flap.
