What the Banshee 12 V jump starter does

The BatteryJack Banshee is a portable 12 V jump starter rated at 800 A peak current and 400 A start current. It targets drivers of vehicles up to 5 L petrol or 3 L and 2.8 T diesel who want a compact backup that also charges phones and tablets via dual 5 V 2 A USB ports.

Sustained-load behaviour

The internal 1800 mAh pack delivers the rated 400 A start current for cranking and can reach 800 A peak for a short burst. A depleted unit recharges in roughly two hours from the supplied 15 V 1 A wall or car charger, so repeated jump-start attempts are possible within a single roadside stop.

Installation and common pitfalls

Connect the alligator clamps to the battery terminals, observe polarity, then press the jump-start button. The main errors are attaching clamps in reverse order, trying to start engines larger than the stated displacement limits, or expecting the USB ports to power laptops that need more than 5 V 2 A.

Questions about this item

Does the 400 A start current or 800 A peak current cause the Banshee Jump Starter to get hot or noisy during repeated use?

The unit has no fan or moving parts, so it runs silently; the lithium pack warms slightly during a jump start but cools quickly between attempts.

What cables or adapters must I already own to charge the Banshee Jump Starter itself?

A 15 V 1 A wall charger and a 12 V car charger are included in the box, so no extra cables are needed to recharge the pack.

Will the 12 V 10 A jump-start output work safely on an older vehicle with a 6 V electrical system?

No, the Banshee is designed for 12 V systems only; using it on a 6 V system can damage both the vehicle and the jump starter.
