works very well except for a small detail,
Verified Purchase(What is this?)
This review is from: PortaPow 2.5A Quad USB Wall Charger with 3 Year Guarantee (UK Plug) (Accessory)
I have an archos 80 cobalt tablet and it will charge this plus a smart phone with no problems. Everything works as one might expect and the led to show when charging is complete are very handy. The unit is neat, well made, there is no noise from the transformer. It also remains cool with the two devices I have charging. The USB sockets are a pleasantly firm fit with little danger of the USB lead not making a good connection. The only problem I have encountered is that the touch on screen keyboard of my Archos tablet no longer types what I am trying to type at times and at times introduces random key strokes when I have the charger attached. I feel there may be some signal being picked up that is interfering with the touch screen interpretation of key strokes.
In some ways this is minor and the time the unit has to be on the charger is less than with the previous charger. The screen is unaffected by this as far as displaying and some keystrokes get through unaffected
I originally thought the tablet had developed a fault but it works fine with a different charger or when this one is unplugged. In spite of this I would still recommend this charger but must deduct one star for the slight nuisance value.
