Renogy REGO 12V 35A AC-DC Battery Charger

Short Product Summary

The Renogy REGO 12V 35A AC-DC Battery Charger charges your 12V battery from 230V mains power with a fast, intelligent adaptive four-stage charge. Part of Renogy's REGO system, it's the reliable way to bring your lithium or lead-acid house battery to a full, healthy charge at home or on shore power.

Why This Product

Solar and alternator charging are great on the road, but you'll often want to fully top up from mains — at home or on a powered site. The REGO 35A does exactly that with a proper four-stage charge profile (bulk, absorption, float and equalisation), looking after your battery and getting it completely full at up to 35A.

Key Features

• 35A charging output – fast top-up of your 12V house battery.
• Wide AC input (180–264V, 45–65Hz) – stable charging on variable mains.
• Adaptive four-stage charging – bulk, absorption, float and equalisation for battery health.
• Broad battery compatibility – lithium (LiFePO₄), AGM, gel, sealed (SLD), flooded and user-defined.
• Comprehensive protection – over-current, over-/low-temperature, short-circuit and reverse-connection.
• IP32 rated with low <5W idle draw.

Ideal For

• Caravan, trailer & camper builds wanting mains charging at home or on site
• Lithium house batteries needing a correct multi-stage AC charge
• Anyone who tops up from shore power before and after trips
