this battery tester performs great and behaves exactly as advertised it’s one of the best value listings here very happy
Customer –
Good device, tested up to 80 watts so far. A lot of very useful features such as capacity and battery resistance
g***r –
Ok

This electronic load is quite compact and doesn’t occupy much space. The packaging includes an adapter DC to USB-C; therefore, you don’t need to use a complete power adapter. Working normally: checked loads until 100 W. The cooler is quiet. Keep in mind that for the ability to adjust voltage, it is necessary to use a trigger.

I am very pleased. I only paid for converters from USB 5V to 12v 1A so I can connect the tester to the powerbank without the need for a network plug. I have concerns about her. In contrast, the device itself is a super thing. It measures everything correctly. I can only join the app on Android. Despite the English version, there are Chinese characters everywhere. If you don’t know Chinese and want a Bluetooth smartphone, I advise you not to. Bluetooth does not make sense here either.

It looks good quality, arrived quite fast and very well protected as physically it has no fault

It came well wrapped in decent packaging, well protected against damaging. It all works are described. Via Bluetooth the evolution of voltage, current and power can be followed in a simple graph on your cellphone. BUT the app itself is very disappointing. Nothing on the DL24 can be controlled via the app. When doing so , voltage spikes appear in the graph, ruining the current graph. The app must then be restarted to get back a usable graph on the screen.

We appreciate your detailed review. We’re sorry to hear about the app’s limitations. Your feedback is valuable to us. We’re actively working on improving the app’s functionality and stability. Please stay tuned for future updates.

The parcel arrived in 16 days by the Ukrmail. Packed in a cardboard box, and the device itself is in a mica shell. The package suits me. Everything is as described. 3D printed housing with a compartment for autonomous power supply. I recommend the seller.

Cool tester. Tested the recently purchased 105 ach liphers with it. There is an application on the phone to which it focuses through Bluetooth, but frankly useless, the schedule on it is not informative and generally stopped working the next day, it crashes with an error. There is a program for a computer, and its main advantage is that it can unload data into an Excel and you can build graphs according to any parameters. I haven’t studied the possibilities of power expansion yet, this is enough for me. At high currents, I recommend measuring the voltage separately from the power (current) wires, because The voltage drop is too strong on them and the readings on the device are underestimated
zahidislam2000@gmail.com –
Thank you for sharing your detailed experience! We’re glad you found the tester useful for your projects. The computer program’s ability to export data to Excel for customized analysis is definitely a major advantage. We appreciate your suggestion on measuring voltage separately for high currents to ensure accuracy. If you encounter any issues with the app, feel free to reach out—we’re here to help!

Very good quality, nice device You should connect 12V for power because on 5V by USB-C it working with problem on lower resistance!
zahidislam2000@gmail.com –
Thank you for your feedback! You’re absolutely right—using a 12V power source ensures optimal performance, especially for lower resistance loads. We appreciate your insights!
