【Upgraded Model USB Tester with Bluetooth, USB Power Multimeter 4-28V 7A LCD USB A&C Voltage Current Power Tester Fast Charge Detection Capacity Measurement, PD2.0/PD3.0,QC2.0/QC3.0

Works great and offers a ton of functionality. Very easy to use and understand. Readings seem on-par with devices double the price.Very easy to throw in a kit with a multimeter and a couple different USB cords.Nice to see the lifetime warranty; hopefully I'll never need it and the device will last, but good to know it's there in case.Glad to see a company/seller that stands behind their product.

This is the best tester for the money. I had a few “high quality” plugs that failed to produce the wattage they claimed to produce. Very easy to use and the big bright lcd screen makes it easy to read and understand. I have an iPhone and with this I can stay away from those cheap expensive cords and avoid damaging my charging port. I definitely recommend picking this up and throwing it in your drawer or bag.

Had to return it. Changing the temp from C to F would not change the temperature scale only the label.

I'm a professional electrical engineer and purchased this to take voltage and current measurements. So far both USB-C / USB-A input methods have been working well and it seems to have a lot of other advanced features. I've also noticed the display is larger and the software has better UX than others on the market. One thing to note is that the PD COM switch should be OFF by default, if ON the tester will override the normal protocols (which adds a risk of damage if used improperly).

So far this has been awesome. It will detect many fast charging functions and you can monitor the amperage, mAh and wattage during fast charging. It is very sophisticated for being so small and has many different settings and features so it is not something you'll be able to completely figure out in just a few minutes. PD mode has to be activated with a switch. Definitely professional grade and would highly recommend. Have used other USB meters in the past and most will block fast charging and the ones that don't typically don't have the ability to track mAh.

It's about as accurate as it can get my cord cycles the volts amps and watts and it's never something different then what the cords is currently saying and there is software for the PC and android you gotta dig a little on the web sight but you can find it also the firmware update you will want to get also but both the software for the PC and the app for the phone both work great And add to the device quite a lot The Android application will connect to the device by Bluetooth. The PC software connects with a micro USB I can't find one thing. I hate about the thing or dislike about the thing except for the fact that I don't know really know what to do about protecting it. I haven't found a case or something to like. Keep it in I'm sure I'll find one but that's being a little nitpicky but still this has got to be the best USB tester there is right now

I wanted to like this and was hoping it would work for me since I was going to use this constantly. So when i received it, and it didnt work like it should have, I was really disappointed. Wasn't easy to use like some may claim, nor was it easy to read, and the design...yeah...all around it was just a let down. It TRIED working the first few minutes but than. ...nothing. the other issue is charging it, you.could see where you plug it in, that a part of the metal part wasn't how it usually is. Hence the issue with trying to charge it. There was also a couple BIG issues that makes for the low star count:1. Price for this...OUTRAGEOUS... nothing fancy or anything so having the price point it's at, I don't understand.2. Instructions for this SO confusing and needed help for it and it said to contact customer service. Hiwever after MANY attempts with ZERO replies, I threw in the towel.To me it's a HUGE HUGE deal breaker when it states needing help to contact etc, and there's no reply after numerous attempts.Overall: Instructions non existent, couldn't get any help, price was absurd. If all these things improved and were updated, than I will re edit and raise the stars.
