    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 there should be a switch to choose between voltmeter ...

    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 with it, works great, and it is very usefull.... 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 USB device is working; estimation of the value ... 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. <50mA near 95% charge 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. Read more

    Pros: Good gadget for those seeking to ser how much energy comes from devices, specially from solar powered devices! Very accurate with both voltage and current. Cons: connection is not very firm, it could be better. It steals a little bit of voltage when in use. Overall: good to know if your charger is stable and safe for a specific equipment. I definetelly ... Read more

    Pros: Works as advertised. No issues so far. Finally I'm able to see exactly how well my various chargers are working. The Nexus 7 in particular is very fussy on how it charges and this product has allowed me to know exactly what is going on. This has also shown me the differences in laptop USB ports - surprising. Cons: None at the moment. Read more

    Just plug and it work. pros: Cheap, easy to use, Easy to read voltage and Amps for a specific device/charger pair. Cons: generate some heat, sometimes block other usb port by design... The review for such a small item should not need to enter so much character. It's just a device that you plug and read Read more

    Impression:Excellent to troubleshoot charging issue;

    Pros: Very simple to use. Only action you need to perform is to plug in this gadget to charger and connect your device with data/power cable to it. Two parameters (amperage/voltage) will be shown on Tester's display. Cons: No toggle for choosing measured parameter. Read more

    Impression:Very nice gadget.;
