ToolkitRC M4AC 30W 2.5A Compact AC Balance Charger (XT60)

The ToolkitRC M4AC is a compact, AC-powered balance charger for 1S–4S drone batteries. It plugs directly into a standard mains socket, drawing up to 30W and charging at up to 25W and 2.5A through its native XT60 port — no separate power supply needed for whoops, micro drones, and 4S freestyle or cinematic packs.

Key features

• Direct AC mains input (100–240V) — plug-and-play charging with no external power brick.
• 32-bit ARM processor drives balance accuracy tighter than 0.005V per cell.
• 1.54-inch IPS colour display (240x240) shows voltage, current and charge status at a glance.
• 200mA per-cell balance current on 2S–4S packs.
• Compact 75 x 54 x 30mm, 120g chassis that travels easily in a field bag.

Specifications

• Input voltage: AC 100–240V (30 W max input)
