Water is ok

Rugged built with IP65 water-resistant and dust-tight, promising a greater durability.

  1. 20000mAh: HULKMAN is made from 4 lithium batteries with 5000mAh, each of which has a voltage of 3.7V. So it's also an ultra-large capacity power bank that comes with 20000mAh.

  2. Juiced up to 18 months: All batteries are affected by self-discharge, which is not a manufacturing defect but a battery characteristic. And the energy loss is sharper when placed in cold. Extreme low self-discharge design and its large capacity enable it to be juiced up to 18 months once it's fully charged. Stow in the temperature from 32°F to 113°F is recommended.

  3. Water-resistant: HULKMAN is drop-resistant and dust-tight with IP65 water-proof. Do not attempt to charge a wet HULKMAN; refer to the user guide for cleaning and drying instructions. Liquid damage is not covered under warranty.

  4. The fastest: Equipped with a 65W high-speed charge, a leading technology in the market, HULKMAN gains the reputation of the fastest charging speed jump starter as it's launched.
