Amazon currently offers the ZeroLemon ToughJuice 30,000mAh Battery Pack for $94 but code UKFFS6JC cuts it in third to $32.99 Prime shipped.
Most backup batteries have delicate skins, but not so with the ToughJuice. The internal cell is encased in two layers of protection — a soft anti-shock shell, with a hard plastic material for impact dispersion. The battery inside is huge – 3 times the average size. At 30,000mAh, there is enough power here to charge an iPhone eleven times over. It has four USB ports, which have a total charging output of 6A, meaning you can easily top up a phone and a tablet at the same time at full speed. Given this functionality, the ToughJuice is also remarkably compact, at under four inches wide.
- Premium li-polymer battery cells

- Enormous 30,000mAh capacity
