Where to Buy ToolkitRC M4AC

It comes with the charger, cable for AC input and a manual.

ToolkitRC M4AC Is A Basic Charger

The M4AC Charger from ToolkitRC is only $25 – probably one of the cheapest LiPo chargers on the market. However, it’s only a 30W charger, only accepts AC, and has only one output port (unlike the M4Q we just reviewed which has 4 separate ports).

It might sound like an unattractive charger by the specs, but it has some interesting features.

Why ToolkitRC M4AC Charger Might Interest You

As soon as you plug in the battery you want to charge, it will start charging right away, you don’t have to press any button. Sure, 30W is not going to be fast, but it’s simple and automatic. You can just plug in the battery and forget about it.

However, I don’t think beginners would appreciate this charger, it’s not as versatile as other more sophisticated smart chargers like the ToolkitRC M4Q or iSDT Q6. And if you charge the inappropriate type of battery due to inexperience it could get dangerous.

But if you know what you are doing, you could get a bunch of these chargers and charge multiple batteries at the same time, because they are cheap and automatic. I only wish it supports 6S batteries, that would make a lot of racers happy.

There is only one button on the M4 AC charger, which allows you to change end voltage (4.20V, 4.35V, 3.85V and 3.60V), and change charging current (0.5A, 1A, 2A and 2.5A).

I also bought one of these recently, but it refuses to move off ‘standby’.

I bought 2 (firmware version 1.02), and one of them decided to only boot up into some sort of factory test mode screen (not the calibration screen). There’s no way to get out of that screen. That and the inability to update firmware means the quality is meh.
