RD UM34C Type-C DC voltmeter ammeter
[Works just as expected. If you want to know how your devices charge or why they probably don’t this is a great tool. You can also export the graphs into an Excel file. The app crashes when you do but the data are exported fine.]

RD UM24C APP USB 2.0 LCD Display Voltmeter ammeter
[Packed perfectly. Wonderful device, support two languages, on both sides of the film, it is not scratch on the screen. The screen is very bright. It is convenient to check chargers, cables, and generally monitor how the device consumes energy-) the work of “sinezuba” did not check. The link can download the manual in two languages, + app for pc. On the device itself there are four buttons, for navigation/settings they are enough.]

RD DPS5005 DC Step-down Power Supply
[All super!!! Prosperity 20 days (rostov region) Track tracked. Packing is just not a punched hopper. Despite the miniature size of the module, it is very convenient to use it. Everything is thought out to the smallest detail. The control panel and display interface is understandable. Build quality is worthy of respect! For connection used a switching power supply 24 v 8,33a 200 w. Clear work, exact values. Irreplaceable suitable for checking leds. Responsible and sociable seller. I turned to him regarding the input current, as i have it more than 1,1 times. A few minutes later the answer came: “there is no limit for the input current.” Thank you very much to the seller. Good luck to everyone! ]
