Key Features of the ToolKitRC C4 55W Charger
The ToolKitRC C4 focuses on essential charging and balancing functions in a small unit.
- Up to 55W input power: The listed maximum AC input power is 55W, while the product description specifies a maximum output of 50W.
- Selectable charging current: Choose from 0.5A, 1A, 2A or 4A, depending on the battery and charging requirements.
- Multiple battery types: Supports 2–4S LiPo, LiHV and LiFe batteries, plus 5–8S NiMH batteries.
- Balance charging: Designed to balance compatible lithium battery cells during charging.
- LED capacity indication: Displays 25%, 50%, 75% and 100% capacity levels.
- Built-in AC input: Accepts 100–240V AC, with a UK AC power cord listed in the package.

Which Batteries Can the ToolKitRC C4 Charge?
Before choosing an RC battery charger, always check the supported chemistry and cell count.
| Battery type | Supported range |
|---|---|
| LiPo | 2–4S |
| LiHV | 2–4S |
| LiFe | 2–4S |
| NiMH | 5–8S |
LiPo and LiHV balance charging
LiPo and LiHV batteries have specific charging voltage requirements. The ToolKitRC C4 supports compatible 2S, 3S and 4S packs and provides balance charging for supported lithium batteries.
LiHV batteries require the correct charging mode and voltage settings for their chemistry. Always select the appropriate battery type and follow the battery manufacturer's instructions.
LiFe battery charging
The charger also supports compatible 2–4S LiFe batteries. LiFe batteries have different voltage characteristics from standard LiPo batteries, so it is important to use the correct settings rather than treating the two types as interchangeable.
NiMH battery charging
For NiMH users, the C4 supports batteries from 5S to 8S according to the supplied specifications. Confirm the battery configuration and manufacturer's charging recommendations before use.
Selectable Charging Current: 0.5A to 4A
The ToolKitRC C4 offers four selectable charging current settings:
- 0.5A
- 1.0A
- 2.0A
- 4.0A
This allows you to choose a suitable current based on your battery's specifications and charging requirements.
A higher current may reduce charging time when the battery supports it, but the maximum 4A setting is not appropriate for every battery. Always check the manufacturer's recommended charging current and the charger's power limits.
The product listing also specifies an output of up to 17.4V at 4A, while describing the charger as a 55W model with a maximum output of 50W. Actual output depends on operating conditions, so do not assume the maximum voltage, current and power ratings can all be delivered simultaneously.
What Does the LED Capacity Indicator Show?
The ToolKitRC C4 includes LED capacity indication at four levels:
- 25%
- 50%
- 75%
- 100%
This provides a simple visual reference during charging without requiring a large display. The product description does not provide further details about how the capacity levels are calculated, so they should be treated as an indication rather than a precision measurement of remaining battery capacity.
Compact Design for Your RC Setup
The ToolKitRC C4 measures approximately 106 × 64 × 35mm and weighs around 165g. Its small footprint can help keep your charging area organised and makes it easier to transport with other RC equipment.
The charger uses an XT60 connector and accepts AC input from 100V to 240V. The supplied package includes:
- One ToolKitRC C4 2–4S AC 55W battery balance charger
- One AC power cord
- One user manual
The included AC cord means a separate DC power supply is not listed as necessary for its standard AC-powered operation. Make sure your battery and connectors are compatible before connecting them.

Is the ToolKitRC C4 the Right RC Battery Charger for You?
The ToolKitRC C4 may suit hobbyists who need a compact AC-powered charger for supported battery types and do not require multiple independent charging channels.
It is worth considering if you:
- Use compatible 2–4S LiPo, LiHV or LiFe batteries.
- Need support for 5–8S NiMH batteries.
- Prefer a simple charger with selectable current settings.
- Want LED capacity indication rather than a larger display.
- Need a charger with a UK AC power cord included.
- Prefer a lightweight charger for a small RC workbench.
If you need to charge several batteries independently, support a wider range of cell counts or use advanced battery management features, compare the C4 with a more capable charger before making your decision.
