ZeroLemon ToughJuice | $40 | Amazon | Promo code RV3FUUG9

I’ve probably seen more USB battery packs than 99.9% of people living on this Earth, but I’ve never seen one like the ZeroLemon ToughJuice before. You get 30,000mAh of juice, five (!) USB ports, including a Quick Charge 2.0 port and a USB-C port, and a ruggedized exterior.

It’s niche, but at $40 (with code RV3FUUG9), it’s not all that expensive for a 30,000mAh power bank, let alone one with so many features.
