What charging and accessory features does it include?

Alongside jump-starting, this MEGAWISE model functions as a 21800mAh power bank with dual USB outputs for charging phones, tablets, cameras and other small electronics. A Type-C input speeds recharging the internal battery from modern adapters or computer ports; a wall adapter is not included.

MEGAWISE equips this jump starter with an integrated three-mode LED light (steady flashlight, strobe, SOS) to increase visibility and assist with nighttime repairs or signaling. The included clamps have a built-in LCD voltmeter so you can confirm battery voltage before making a connection, reducing guesswork and improving safety.

• Three LED modes for illumination and emergency signaling
• LCD jumper clamps showing battery voltage prior to connection
• Polarity and short-circuit protections avoid accidental damage
