Very useful unit on a multi tester

This unit is really great for testing the different USB chargers I use to charge my phone. Now I know which adapters charge really fast and which ones give off less power. The Bluetooth feature allows me to check other devices without having to connect to the device itself.

Pros
  • Decent performance
Cons
  • So far so good

Amazing Bluetooth Power Meter

. This is an amazing bluetooth power meter. I'm measuring the power on several small Odroid computers, some at 12 volts and others at 5. This works fine. Sometimes Bluetooth reconnecting fails, but this can be fixed by removing the device and then repairing it.

Pros
  • Certified
Cons
  • You can choose a newer model

practical USB tester - tester

I've only had this tester for a few weeks and I'm very happy with it so far. Good big bright screen, very useful when testing USB parameters (volts, amps etc) to identify USB cable problems etc. I also plan to use it to test some power supplies for nominal capacity. Very happy with this purchase, I recommend.

Pros
  • Lots of positive emotions
Cons
  • Price

Works almost - Tester

Good size and accuracy. As a standalone device it is very good. As a remote data logger, it's hard to recommend. I'm trying to use its Bluetooth as a serial RFCOMM device connected to a logging application on a PC. The device keeps disconnecting and not reconnecting. Bluetooth crashes after a few minutes on multiple (two) PCs, tablets and an Android phone. On a PC, communication can be resumed by programmatically disabling and re-enabling the associated COM port, which is a fairly complex…

Pros
  • New
Cons
  • Tape

easy to read display

Summary: I bought this to measure USB charging current, specifically I bought an ultrasonic dog bark device and the power LED kept flashing after a few hours so I guess that the battery charging process is finished. In the first picture, the charging current is 393.4 mA and after 30 minutes it has dropped to 70.4 mA, so charging is complete. Pros: Good fit and finish, easy-to-read display (compared to the smaller screen in the photo, details below). Cons: Bluetooth didn't connect (phone said it

Pros
  • easy to use
Cons
  • something else

The hardware is excellent as evidenced by online reviews and use by many trusted electronics educators. However, the software (PC/Android/iOS) and documentation/manual is very challenging, 3 star rating. Presumably it's software and iOS software, but it took a list query to find it on the App Store, which still doesn't indicate the existence of an iOS app. When the documentation is accessed via a QR code on a card in the product box, it leads to a file-sharing site full of virus ads that try to

Pros
  • Best in niche
Cons
  • Poor performance

Truly unbelievable! - Tester

Excellent tester! I really like the upgrade from the A3-B that I have. The screen is flush with the face and appears much sharper and a bit brighter. Colour, brightness and display orientation are easily adjustable. Power can be USB-A, Micro-USB or USB-C and can be transmitted through different connectors (e.g. Micro-USB in and USB-A out or USB-A in and USB-C or C-to-Output). -C.) I haven't tried every combination, I don't think C->A works for example. The Bluetooth interface for the Android

Pros
  • Easy setup
Cons
  • Doubt

Ruideng UM25C Bluetooth USB Power Meter ideal for hackers and geeks

Most of the good reviews on this unit are for the Ruideng model, I don't know if there are any replicas as it's sold under different brands by many vendors, but this unique design works very well functionally. The company has introduced many models and whoever develops them is worth seeing as they know their stuff. So if you want a Bluetooth USB power meter, getting a real Ruideng is a must. The product photo shows a USB test load, which is not included in the scope of delivery. Because devices

Pros
  • Absolutely amazing!

  • Almost never
