RD DPS5005 DC Step-down Power Supply
[Good set, a little soldering. It is a pity that there was no connector for connecting the cooler, i had to cut off the wire. Complete wires are enough to collect all together. The first inclusion was smoke test.]

RD 33v10A 7in1 OLED Multifunction Tester
[Delivery to the motherland of lenin 14 days. Packaging worthy (foam, pupyrka, scotch). Starts working from about 3,7 v. Measures, for its cost, exactly. Of the minuses: small numbers on the display. In my opinion, you can add switching screens with each parameter built-in button on the ring, but with a large font. The work of the seller and the goods was satisfied]

RD Tech, I don’t think you need to put up reviews of your products anymore.

We already know they are very good.

[Excellent tester. All functions in one review do not describe. I advise you to look at the reviews on youtube. The device is neatly assembled. The protective film slightly departed when i disassembled it to look-it still needs to be removed. The device came in time, the seller communicates well, gave a voltmeter. ]

RD HD25 HD35 Electronic USB Load
[The workmanship is excellent. With usb load, you can quickly and efficiently check the charger or power bank, check the maximum output current with the output voltage check and immediately determine the power source. The load also allows you to determine which fast charging standard supports the charger or power bank. You can manually switch the checked device to the desired standard of fast charging. You can also check and evaluate what current is able to miss the charging cable. The presence of 3 different connectors allow you to check the micro usb cable, USB-C, usb extension cable. Excellent tester for checking chargers, power bank and cables. Also, the HD-25 can be used in amateur radio practice as a load to check the setting of power supplies, etc. Devices in the range of output voltages 4-20v and current no more than 4a. I recommend this seller. I personally made sure that the quality of the goods, packaging and delivery are excellent. ]

I bought a few of these in the past from RD tech on AliExpress. All came and working well.

 

Some AliExpress sellers might not be so reliable; I had two items with issues and 1 shipped but never arrived; seller did not issue refund.

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! ]
