Does not require batteries

Reviewed in the United States on March 24, 2024

I almost didn't order it because I read that it needed batteries to operate. That is incorrect. It pulls power from the USB port like most of the other USB testers. Works well! Inexpensive too.

It Does the Job...inexpensively!

Reviewed in the United States on May 13, 2023

Verified Purchase

Purchased to determine the current draw of misc. USB devices when drawing power from USB ports. I particularly like watching the output voltage change from initial power application (especially when CHARGING) to actual utilization as the current draw fluctuates.

Pluses:
1) it has STANDARD (Type "A") USB male and female connections. This makes it a (more or less) UNIVERSAL device for the majority of USB cables.
2) It's PRETTY CHEAP, compared to comparable units, so it won't be (much of) a "drain" on the finances.

Minuses:
1) The current meter only has 10 mA (0.01 A) precision, which means "light-duty" devices don't "register" any current draw. However, that's no big deal as the majority of my devices usually draw a minimum of 10 mA (0.01 A).
2) The display is "kinda small", meaning you have to "get close" to read it. Thankfully, it is ILLUMINATED and "high contrast", making it very readable even in "brightly lit" areas. Nevertheless, if you have "aged" eyes, you may need a small magnifier to read it.

Otherwise, I ** DO INDEED ** recommend this device, especially given it's VERY INEXPENSIVE cost.

Useful Tool - Unique Benefits

Reviewed in the United States on August 16, 2019

Verified Purchase

Just received the devices and it is in good working order. I will update the review if my experience changes.
The device is small and the display is also small, but with the backlight it is very readable.
Values for voltage are very accurate, can not verify the accuracy of current draw but it seems at least roughly accurate within bands (i.e. <1A <0.5A 2.0A).
This device has both USB A and micro usb inputs. That unique feature allows testing of wall warts that terminate as a micro usb and also allows comparative charging cable testing (to check for poor charging cables with large voltage drops).

It's good for basic testing but lacks some features

Reviewed in the United States on November 30, 2023

Verified Purchase

The media could not be loaded.

Detects voltage, bright screen knows when it's being short circuitry, like younconmey it to itself. Good for like an arduino project or testing chargers and battery packs. Same company also has a usb c version. I ordered both and this one took longer to get here and I didn't need 2 so I will return it, due to the long shipping delay, but ingive it 4 stars because it does what it says and you can actually test micro USB power out too and test 2 devices at once. 10 modes for seeing different devices yountested but limited features.

Overall I would use it solely to make sure my products were authentic.

I am the CMMS (Computerized Maintenance Management System) administrator at our company. We have 22 tablets / 22 chargers. We had an issue with some of the tablets depleting battery charge before the end of an 8 hr shift. Not all, just a few. Using this device we found three defective chargers. Chargers replaced, techs were happy again. Techs happy, I'm happy, managers happy. Oooorah!

compared to a Ruideng UM25C, the Ah readout is about 3-5% off after a weeks use. This is not bad, given ordinary references used will likely be in that range for low cost devices
