Nitecore NB Air Ultra Lightweight and Slim USB-C 5000mAh Power Bank RG316 I ran this battery asI love a great battery bank. This one is incredibly lightweight and produces a constant 12v output when paired with the proper 12v module. I ran this battery as seen in the photo for a weekend camping trip and logged 142 contacts on the MTR 3b! It had 15 20% charge left at the end. I was very impressed so I now offer these in the store. This is the smaller of a few options from Nitecore. This bank is rated for 1. 5a at 12v but my testing showed 2a
