ToolkitRC M4 Pocket 80W

ToolkitRC M4 Pocket is a pocket-sized single-channel charger without an integrated power supply for 1-4S LiPo, LiHV and LiFe batteries, with up to 80W of power and a charging current of up to 5A. It measures 80x40x30mm and weighs 75g, so it fits in a pocket or a small backpack and is especially suitable for field use. The XT60 and XT30 output connectors are built directly into the charger body, allowing batteries to be connected without a charging cable or adapters. The balance port is located on the side.

The charger does not have an integrated power supply. It can be powered either via XT60 with 7-25V DC voltage (max. 5A) from an external power supply or battery, or via USB-C (5-20V) with support for QC, PD, AFC and FCP fast-charging protocols, including from a USB adapter or power bank. Full 80W power requires a sufficiently powerful supply. With 4S batteries, the 5A current is limited by the 80W power limit, indicated on the display by the “P” symbol. The USB-C port also serves as a 5V/1A output for charging a phone or other small device.

It is operated with a single button. A short press selects the charging current: 1A, 2A, 3A or 5A; a long press selects the cell termination voltage: 4,20V (LiPo), 4,35V (LiHV), 3,85V (storage voltage, “storage”) or 3,60V (LiFe). The termination voltages can be adjusted in the calibration menu (TVC function) with ±10mV accuracy, and cell voltage measurement can be manually calibrated using an accurate voltmeter. After every power-on, the charger is locked (“Lock”) and unlocked by pressing the button, preventing accidental changes to the battery type or current. Charging starts automatically once the charger detects matching voltage at the main and balance connectors. The balancer operates at 400mA, and charging accuracy is below 0,005V. We recommend charging at 1-2C, for example, a 1000mAh battery at 1-2A, which extends battery life.

The colour 1,54" IPS display with 240x240px resolution shows charging time, input voltage, charger temperature, battery and individual cell voltages, charging current and charged capacity. It also indicates whether the charger is currently limiting the current due to power or temperature. Heat is dissipated through ventilation openings in the housing. The manufacturer does not specify a discharge function.
