50A 12V Engine Start Charger

The Tank Brand charger delivers up to 50 amps of engine-start current and adjustable 2–20 amp charging for 12-volt batteries. It suits cars, motorcycles, boats, farm machinery and RVs that need reliable starting power and routine maintenance charging.

LCD Screen with Smart Charge Logic

A built-in LCD screen shows real-time status while Smart Charge logic automatically selects the appropriate 2A, 5A, 10A, 20A or 50A output. The unit accepts 120–230V AC input at 50/60Hz and includes multiple connectors for quick attachment to different battery terminals.

Replaces Basic Trickle Chargers

This unit replaces simple trickle chargers that cannot crank an engine or adapt their rate. The jump is worth it when a vehicle sits for weeks and needs both a maintenance charge and the ability to start a dead battery without a second vehicle.
