The most important thing for me was the ability to use the charger while hiking. I love how it attaches to my backpack so I don’t have to worry about losing it. The rubber “bumpers” keep water out as long as you keep them closed tight. The only complaint I had was with the rubber around the outlets. Sometimes it’s a bit hard to close them and they must be closed to keep water out. It’s not really a big enough complaint to lower the rating as I haven’t found a solar charger this small that can perform the way I want it to while hiking or traveling. Also, the charger is only meant to be waterproof in the rain or snow, not when submerged.
I like that there are two outputs for charging two smaller devices at a time. The right side is the quick charge and my phone does charge quicker with the 2.1A USB port than the other. When the charger was fully charged, I was able to charge my iPad from 35% to 100%. I was pleasantly surprised it was able to handle the bigger device at all. With the 8000 Amh power, it is more powerful than the other portable chargers I own. I also like that it comes with a light. While it’s not super bright, it does give off good light to be useful in an emergency.
I’m happy I’ve found a charger reliable enough as an emergency backup while hiking. My phone is my lifeline when hiking alone and I have to know it will have power no matter how long I hike.
