Lenmar Mutant 20,800 mAh Charger
Next is one of our biggest and most capable portable chargers. We'd hardly call it portable, but this beast can charge four devices at once, and has enough juice for three of those to even be tablets.
Coming with two regular speed (iPhone) USB ports, and two high-speed 2.4 amp output USB ports, you can charge four devices at once using the integrated 20,800 mAh battery. It has a simple on/off switch, four LED lights to show you the remaining capabity, and some of the best shelf life of any charger from our list.
I can charge the Lenmar Mutant with a wall outlet, leave it in my truck for 3 weeks, and have 80% remaining when I actually need it to recharge my tablet, phone, accessories, vapors, iPod's and more. This is my favorite charger and one I use the most, even if it's one of the biggest.
If you truly need tons of portable battery for a camping trip, an all night business meeting, or just like charging your phone, tablet and more at the same time. Get this bad boy. I use mine a at least 4-5 times a week, and it's been running strong for 8 months. It's big, expensive, but worth it. Oh, and for those who truly are nuts, get the ZeroLemon 30,000 mAh Charger.
