HAUSPROFI 20A 12V/24V Car Battery Charger Trickle Maintainer Pulse AGM LiFePO4

About this item

The Hausprofi RJ-E122001B is a smart plug-in charger that lets you set the exact charging current between 1A and 20A for anything from a motorcycle battery to a large truck or RV battery bank. It automatically switches between 12V and 24V systems and has a dedicated lithium mode, so one unit covers AGM, GEL, SLA, Flooded, Calcium, Deep Cycle and LiFePO4 batteries up to 300Ah. Built-in temperature sensing adjusts voltage for hot or cold weather, and the memory function picks up where it left off after a power outage. Note: this is a charger/maintainer, not a jump starter — it needs to stay plugged into an AC outlet while charging.

• Adjustable 1A–20A output for 12V and 24V batteries, auto-detected
• Charges AGM, GEL, SLA, Flooded, Calcium, Deep Cycle and LiFePO4 (lithium) batteries safely, up to 300Ah
• 0.3V low-voltage activation with 9-stage pulse repair mode can revive deeply discharged batteries
• Automatic temperature compensation (-4°F to 113°F) and memory function that resumes charging after a power cut
• Long combined 150cm AC + 90cm DC cable, flame-retardant ABS housing, cooling fan and 8-point safety protection
• Plug-in charger/maintainer only — not a jump starter, requires an AC wall outlet
