Mastervolt Charge Mate Pro 90

Mastervolt Charge Mate Pro 90 — 90A Multi-Stage AC Charger

Premium shore-power battery charger with 90A output. LiFePO4-optimized multi-stage charging profile. For van and off-grid builds that want a dedicated AC charging solution independent of an inverter/charger.

Key Features

• 90A DC output — charges a 200Ah LiFePO4 bank from empty in ~2.5 hours
• Multi-stage charge profile tuned for LiFePO4 (also AGM, gel, flooded)
• Works with 120V or 240V AC input (auto-sensing)
• IP-rated enclosure for marine/mobile installs
• Multiple outputs — can charge multiple banks simultaneously

When to Pick This

• Builds where you already have an inverter (don't need combo inverter/charger)
• Large LiFePO4 banks that want fast shore-power top-up
• Alternative to Victron IP22 for MasterVolt-ecosystem builds

Not sure what charger size you need? Use our free Power Station Size Calculator to size your battery bank first — a good rule of thumb is charger output = ~50% of battery Ah capacity (so 200Ah bank → 100A charger).
