This tester is great!

This is my second purchase of this product, the first was given to a colleague as a gift. This multi tester is great, I checked all my USB network connections to check the output and even tracked the battery levels of devices (phone and tablet). I haven't installed or used the alerts feature, but this can be useful when doing long-term trend analysis. I never knew how much I needed something like this until I bought it. You know, I can't imagine not having it.

Pros
  • Top marks for support and durability from testers
Cons
  • Not bad, but...

I'm glad I bought this USB multimeter.

I used this USB multimeter to test the output current from different outputs of two 5 output chargers on five different devices and to compare it to my Fluke. 87-B (one of the best multimeters). While not high res, Fluke agrees. This allowed me to find an almost dead slot on one so I could stick it on so I didn't use it. While I trust Fluke more and expect it to be much more accurate, it's designed to plug into USB ports and I don't need four decimal places for that purpose. One or two is…

Pros
  • New
Cons
  • Mostly ok but...

Not intuitive but works as described

Only used 1 day but seems to work as described. I can't verify the readings, but they're in line with my expectations from the usual tests I've tried. The instructions were difficult to read due to the very small font with black text on a glossy blue background. All control is done with a single button (on the back of the display), but after reading the instructions a few times and playing with the button as instructed, I finally figured it out. (If I could, I would change the short press and…

Pros
  • Robust workmanship
Cons
  • Secret

Handy USB power meter

This USB power meter supports additional USB 3.0 pins, which is an upgrade from my previous USB power meter. I also like its shape, my previous USB power meter had a strange shape that sometimes disturbed its use. It is convenient when all measurements are displayed on the screen at the same time. The button on the back is covered with a sticker and is not immediately noticeable. I was testing the current draw of a USB powered microcontroller when this power meter turned it off. "UCP/OFF"…

Pros
  • One year trial
Cons
  • Issues

This purchase cost me a lot of money!

I am very satisfied with my purchase of the Drok USB3 multifunction tester. I also bought the DROK Micro Load Battery Tester Board USB 0.15-3A 15W Adjustable DC Electronic Load, Aging Tester with Smart Detector, which I highly recommend if you want to do any type of analysis on your chargers and batteries. That's why these excellent tools cost me so much money. I started testing all my USB chargers and power adapters and found that about 70% of them were useless and couldn't maintain an…

Pros
  • Absolutely amazing!
Cons
  • Minor problems

It's a great value for a handy, portable USB 3.0

. It's a great price for a handheld USB 3.0 portable tester, but a bit pricey ($29) for use as a constant charge controller, in my opinion. Li-Ion batteries last longer if you don't fully charge them, so I use the UC (Low Current) auto shutoff to stop charging my tablet when the charge current drops below 1.2A - at which point it is my tablet charged to 80%. Without this device, it would charge at 100% and draw around 0.4A indefinitely. My only functional complaint about the DROK is that once…

Pros
  • . Excellent overall performance.
Cons
  • . Doubtful.
