RIVACASE VA2537 has a capacity of 10 000 mAh – enough to fully charge iPhone 11 two times, while RIVACASE VA2574 packs a massive 20 000 mAh battery, which should be enough to charge most phones about four times.

Both batteries feature two USB ports each and allow you to charge up to three (!) devices at the same. Tap the power button and you can see the remaining power - LED lights indicate charge level.
