ToolKitRc M9 review: The talking drone LIPO charger

In addition to the lots of inbuilt functionalities, the ToolKitRc M9 features cool voice alerts and a multi-angle colour display. With a size slightly bigger than your smartphone and output power of 600W, it is very portable and powerful. Is the ToolKitRc M9 the only charger you need on your drone backpack? Let’s find out from this review!

Along with all electronic gears, battery chargers also evolved a lot in the last few years. Now, they are smaller, much more powerful, safer, and packed with tons of handy features. The ToolKitRc M9 is intended to be used in both ways, as a field and desktop charger. Featuring a wide range of input voltage (7~35V), with the right adapter, it can be powered from your car’s cigarette lighter socket or a high-capacity LIPO pack. Thanks to its 65W USB Type-C out, it allows charging your drone battery, mobile phone, tablet, and even your laptop.

ToolkitRC M9 review

Disclosure: I received this drone charger for a product review collaboration with TooltikRC. Product specs and quality may vary according to the manufacturer’s reliability, so I cannot guarantee that you will get a charger that performs exactly the same as seen in my review.

ToolkitRC was founded in 2018 and is committed to developing, producing, and selling intelligent and easy-to-use RC accessories. Their product range includes multifunction tools, basic chargers, testers, and adapters. The M9 is their latest multifunction charger designed for those expecting more than just basic functionalities.

The M9 multi-charger comes in a compact box with a USB-to-USB cable, screen protector,  and quick start guide included. No AC adapter or at least an XT60 to DC adapter is provided. Probably it is intended to be used as a field charger by using a high-capacity LIPO pack as a power source. You will not fly in the following days if you have any fully charged LiPo. You can transfer the energy back to the big battery. It will not save the earth, but it is still a great feature for transferring energy from one LIPO to another.

ToolKitRc M9 measures 108*71*36mm and weighs just 235 grams. On the back, there is a power input XT60 plug (7-35V), a micro SD slot, and a loudspeaker. The XT60 output and 8S balance ports are on the opposite side, along with USB Type-C and Type-A ports. It has a temperature-controlled cooling fan on the left side that starts only when needed. I like that the charging XT60 port has an RGB LED that lights in different colours, according to the working type.

By default, the PWM/PPM/SBUS signal input/output ports are invisible. You need to remove a plastic cover to be accessible and usable hardly.

Display and Controls

Probably the sweetest thing about the M9 is its foldable colour display. The IPS LCD has a resolution of 320*240 pixels and its angle can be tilted by 0-80 degrees. You can choose from multiple themes (colour schemes). I find the dark mode more friendly with your eye than the default theme.

In addition to the handy metal jog wheel with a push function (OK), there is only a single button (Exit). Navigating through action menus\program configuration\system settings is easy and intuitive. By scrolling up/down, you can navigate between pages and menus. Press shortly to set charging parameters or press and hold to enter in the system settings interface.

Voice prompts confirm every action. Initially, I thought that is funny and useful at the same time, but after a few usages, I found it annoying and without much sense. Instead, the customizable start-up logo is very cool.

Working modes

Like most computerized chargers, the ToolkitRC has 3 main functions: Charger, Discharge, and Storage. Before starting, you need to select your battery type. The M9 is compatible with the most common rechargeable chemistry standards (Lipo, LiHV, LiFe, Lion, LTO, NiMh, and PB). You can charge up to 8cell LIPO batteries once at a time or multiple using a parallel breakout board. The charging current can be adjusted on the fly if you want to speed up the process.

You can opt between internal resistance (Up to 3A), Recycling – Battery to Battery (up to 20A), or External Load for discharging.

LiPos should be stored at room temperature at ~3.8V/cell for the longest lifespan. Most modern smart chargers, including the ToolKitRC M9, have a ‘Storage’ function that will either charge the LIPO up to that voltage or discharge them down to that voltage, whichever is needed.

Price and availability

The M9 multi-function charger can be purchased from various ToolkitRC partners. Currently is available at Banggood for only US$72.99 with 9% off. Additionally, you may need an AC/DC adapter and XT30 to XT60 converter. ToolkitRC has two compatible power adapters, the ADP180 (19.5V-XT60 @max 180W ) and ADP100 (20V-XT60 @max 100W). With almost zero cost, if you have an old laptop charger, you can easily replace the stock plug with an XT60 one and use it with the M9 charger.

Extra features

1. Internal resistance meter

The internal resistance of both the LiPo pack and the individual cells within the battery is one of the very best ways to monitor your battery’s condition. Using the ToolkitRC M9, you monitor the internal resistance during the entire charging process.

2. Power source mode (DC to DC converter)

The built-in adjustable power source is a handy feature when you want to test a new device without a power adapter. You can set anything between 1 and 35V by 0.1V steps regardless of the input voltage. The output current can be set from 1 to 20A (the input source must have sufficient power).

3. Measure the signal and Generate a test signal

The M9 charger can also measure and generate PWM, PPM, and SBUS signals. For example, while the “PWM measure” allows testing each individual channel of your radio receiver, the “PWM signal out” can simulate an 8CH transmitter to your flight controller.

4. USB phone charging

The ToolkitRC M9 has two types of USB ports, Type C and Type A. During charge, you can monitor Voltage, Current, Capacity, Elapsed time, and Protocol. My Samsung S21 detected the M9 as a ‘Superfast charger’. Through the USB ports, you can charge not just smartphones but also gimbals, remote controllers, action cameras, and many more devices. The 65W output allows charging even your laptop in no time.

Safety Recommendations for LIPO batteries (Using, Charging, Balancing & Storing)

• Always store, charge, and discharge your LIPOs in a charging-safe bag (nonflammable container);
• Do not store your LiPo batteries in extreme temperatures below 0C or above 50C;
• When storing batteries for extended periods, store them at a half-charged state;
• Always use dedicated LiPo chargers like the M9;
• Double-check settings before starting any charging program (Chemistry, Cell Count, Current);
• Ensure that charging leads are connected correctly;
• Never, under any circumstances shortcircuit the battery (positive and negative leads touch each other);
• Never leave charging LIPO packs unattended;
• Do not overcharge or over-discharge batteries;
• Never use a LiPo pack that is ballooned or has damages due to a crash;
• Dispose of LIPOs by fully discharging and returning them to a local battery recycling facility.
