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.

The 65W charging speed means you can charge the Alpha jump starter with the original wall charger at 65 watts. Using a wall charger from another brand can’t achieve the 65W charging speed.

An IP65 rated enclosure gives protection against low-pressure water jets from any direction, as well as condensation and water spray. It’s suitable for most outdoor enclosures that won’t encounter extreme weather such as flooding.

1. Alpha 65 comes with a 10W wall charger, and the SC 65W wall charger needs to be purchased separately.
