At first, l thought there's a crack on the LCD, it turned out it was just the protector. l was able to test my old batteries and proven that my 19800mAh was so fake. Thank you!

Cool product to test Li-Ion batteries. The PCB is all ptinted in Chinese but with the QR code you'll come to an English side which explains very well the functions of the tester. I think for 10 bucks its a great product. But you should waint until theres a sale, because you can easily get it for less money.

The device works well, be mindful that only the right side is used for operation. The left one is only used for power supply and keeping the screen on while discharging. Banggood is always a top service, received in only one week.

It arrived OK. It is easy to use and provides good information about the tested 18650 batteries. I bought it because of the LCD, as it gives much more information at the same time than the previous LED-only device. The discharge-charge functions work well. Big problem, sockets hold the batteries very roughly. They have to be stretched, during which their contacts and insulation can be damaged, which happened to me. The sockets had to be replaced with a more manageable one, which caused additional costs. Apart from this error, the capacity meter can be used well.

meg kaptam a terméket! de az LCD kijelzőn van eggy jelölés és el van repedve!

works very well. I added an additional heat sink to the 2 power resistors.

Funktioniert sehr gut. Die 2 Leistungswiderstände habe Ich mit einem zusätzlichen Kühlkörper versehen.

Works as expected. I will add a little fan to cool the resistors and extend the lifetime of the device. To change language hold the left button while powering on!

Very good product. Charges and discharges 18650 batteries with reading capacity. Very useful for sorting used batts. Very readable screen. Missing the user manual, present on the internet.

Très bon produit. Charge et décharge les batts 18650 avec lecture capacité . Très utile pour tri des batts usées. Ecran très lisible. Manque le mode d' emploi, présent sur internet.
