  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. Pre-Heat technology: The lowest temperature that HULKMAN can work is derived from tested information from the lab under very restricted conditions. It will automatically warm up itself to improve the battery performance when detecting the temperature drops below 32°F.

  3. 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.

  4. 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.

  5. 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.
