ac to usb Customers Reviews

  • Great and useful item for travel and get energy from car to devices.

    posted by nicolasantoci

    The product is very simple to use and is very useful for uses in travels. It comes with a fan to cool the system and also with variable internal resistance with temperature for protection.You can connect all common connectors of 220v or USB cable. It is compact and durable.It comes with an internal fuse that can be seen by removing the red plastic cap. It's like those who come in cars (rectangular).
    Nothing to say.
    It is a very good product and convenient for travel without problems of charging energy of our devices.
  • Excellent product just perfect

    posted by xandynhu

    I have many hard drives and CD-ROM that I had to test or backup manually and it always took a long time. Today I no longer have to worry about, these tasks will now be implemented without delay.I tested all kinds of HD and some CD-ROM has been completely satisfactory, it was recognized only by plugging without requiring the installation CD in no time I was done, I really could not be happier.
    Speed is not the strong point but also is not really a problem, do not advise the use as external HD, it was not made for this purpose although everyone uses, should not fall in any way, I made a case for the adapter and I believe it is mandatory to use one, any fall can damage the product.
    By the size so small, efficiency, versatility and low price is not impossible to buy, is really a dream for any computer technicians, technicians did not know some friends that this product existed. Thanks DX
  • Handy Power Supply for USB Gadgets

    posted by BrunoDPO

    + Bivolt, so people don't have to worry about in which voltage this power supply works.
    + It provides the default USB 2.0 power, 5V.
    + Handy, lightweight, practical... Do I need to say more?
    * I wonder if it can be used for supplying power to SKU 3916. Some people said that it does not work for all the USB gadgets, but I haven't tested it massively yet to say. It just worked fine with a Motorola Z3 cellphone and a Napoli MP4 Player.
    It's a great item for charging a MP3 player, some brands of cellphones, or even for providing power to a USB gadget. Not to mention its ease of use, just plug and play! =D
  • works great

    + unbeatable price + works great + looks great + tested by powering 700W angle grinder during cuting 16mm thick steel rods + it is capable to power my TV with DVD player + nice solid aluminium chassis + easy to install + comes withe everything needed to installation
    I am using this device on my cottage, where is no source of electricity but batteries. Until now I was limited to using only 12V powered devices.
    worth that price
  • Good for its price BUT HUGE VOLTAGE PROBLEM

    posted by shushahar

    Built quite good, a cooling fan, solid box. All protections needed are there - over voltage, under voltage, heating, over current. the price is fair for this size. comes with gators to use.
    good if it fits your battery
