Tank Brand Multi-Rate Charger
The BatteryJack Tank Brand unit is a 12 V automatic charger that delivers selectable outputs of 2 A, 5 A, 10 A, 20 A and a 50 A engine-start boost. It suits owners of cars, motorcycles, boats, farm machinery and RVs who need one device for routine maintenance and occasional jump-starting.
Interchangeable Connector Set
The package includes multiple connector types so the same charger can attach to top-post, side-post, ring-terminal or SAE-style battery terminals without extra adapters. This flexibility lets the user move between vehicles and equipment quickly while keeping a secure, low-resistance connection.
Rugged Case With Wide-Range Input
A black and yellow impact-resistant housing protects the internal circuitry in workshop or outdoor environments. The charger accepts 120–230 V AC at 50/60 Hz, so it operates from standard household or light-industrial outlets worldwide without a separate voltage selector.

Questions about this item
Will the internal cooling fan need replacement after heavy use?
The charger uses passive cooling with no internal fan, so there is no fan to replace during its service life.
Which protection circuit activates first during a prolonged 50 A engine start?
The thermal overload protector trips before any other limit when the 50 A engine-start mode runs continuously.
How loud is the unit when it runs all day in 20 A charge mode?
It operates silently because the design has no moving parts; only a faint transformer hum may be heard in a quiet room.
