Pro: cheap, useful, easy to use, fast to use
cons: It is upside down for my use.
It will help anyone to measure any USB device. You just simple plug it and use it, really simple. I use it to measure the consumption of my first MP3 player, my mini-drone charger, and even my second mp3 player. It also ... Read more
Pros: It's a very neat current measuring device, it looks sturdy build. the connectors are good. display is clear and bright enough to read from a distance. the display changes from voltage to current each few seconds this makes it easy to read and understand. Cons:
The shape of this thing, as the connectors ... Read more
Pros: Good Quality and does what it should.
Cons: Kinda pricey, well at least when i bought it. Wish it had LCD reader on both sides cause sometimes some of my AC usb wall charger makes the screen face the wall so you can't watch it unless you up against the wall. But other than that it's a great product ... Read more
pricing is cheap compared to ebay etc.. Product is good though i would not give 5 star bcs of two reasons
sometimes the charging time is more than what it used to be without the device (I have never seen an current reading of more than 1.2A (mostly 900mA) though my charger and device supports 2.1A) second ... Read more
Pros: Very good to evaluate, in my case, the amps to charge devices and to see if the correct voltage is beeing pushed to the device. You can also see that when a device is charged, if amps keep beeing pushed in (wich is bad) or if ot drops to a very low amperage. Cons: So far, none :D Been very satisfied ... Read more
Очень понравилось это устройство. Правда не ко всем USB можно подключить. Но такова конструкция. Хорошо проверять потребление по USB подключенным устройством. Мне понравилось. За небольшие деньги вполне нормально. Read more
Pros: Very simple to use: when there is at least some current and voltage on USB, it repeatedly shows voltage and current. A "must have" thing when you need to test if there is electic voltage and current. Typical scenarios are: testing USB chargers; testing USB ports on computers; testing if peripheral ... Read more
A bit of a geek, novelty item...but I'm still impressed.
It let's me know when my phone is charged. Better than the indicator on the phone, since I don't have to turn the phone on. I can easily see the display from across the room. When charge current drops to < 100mA, I know that I'm +90% charge. <5... Read more
Pro:Both Voltage and Current is measured. Display is alternating between showing Voltage and Current. Very easy to see if your USB is within specifications.
Cons: Not ,much at this price. It doesnt fit all USB ports due to the mechanical size. If was made as a cable then more possibilities.
