Asus Eee Pad Transformer power adaptor launching tomorrow – for £24.99

We’ve not been paying too much attention to the Android tablet scene, to be honest, but one thing we have noticed is a sort of CONSTANT CLAMOURING by Eee Pad Transformer owners for additional chargers, so they can leave one *there* and another one *over there* and free themselves both physically and mentally from… anyway.

In quite possibly the most boring news we’ve written since that one about BT business services apps, we’re pleased to let you know that this…

asus eee pad transformer power adaptor

…the ASUS Eee Pad Transformer TF101 Adapter (with EURO & UK Plugs) will launch tomorrow, and will be available direct from Asus UK for £24.99. Hooray for that. The reason you can’t use normal USB to charge big tablets is to do with how batteries work. We’ve learned a lot today.

    Lol thanks I’ve been waiting for this to come out

  2. That’s because it’s a USB3 charger, at 15V and something like 5A max. The Asus will only trickle charge from other USB2 chargers. This charger is a piece of c**p anyway. The first I had was dud, the second fell apart. Extremely bad design – I’ve no idea how it passed the CE test.

    Just to point out, you CAN charge your Asus Transformer over USB, but it’s sloooowww.. That’s because USB1 and USB2 ports on your computer only support 5V and 500ma

    The wall charger does not have this limitation an can send more juice…

  4. Actually it’s more complex.
    USB 2 only allows a maximum of 0.5A. But USB 1.1 only allows one setting – the ‘maximum’. In the past this was 0.5A. But gadget and USB makers soon took advantage of this loophole to make USB 2 ports in USB 1.1 mode to give out 1A.

    So as long as the gadget doesn’t pretend to be USB 2 then it will try to draw current at whatever it can. So 2.5″ external harddrives often take 0.6-0.7A. Which is why they often come with a USB port splitter cable to use if your USB port can only manage 0.5A.

    Most gadgets like smartphones use up to 1A. So USB chargers sold by Maplin use this USB 1.1 loophole to provide a cheap charger for less than a tenner.

    USB’s offical answer is to place a low ohm resistor across D+ and D- pins which modern USB 2 & USB 3 gadgets detect this and allow high current loads.

  5. I recently got a new ASUS Eee Pad Transformer shipped to Canada from Thailand and it came with the European charger which is not compatible with our outlets here. So, I went to Staples today and bought a regular USB to AC adapter/charger but it does not appear to be charging my new tablet. It’s beginning to look like I have no choice but to purchase an actual ASUS brand charger such as this one. Oh well, at least now I know!

      Hi Darryl,
      I have the opposite problem. My Transformer has only the US & Canadian adapter and I need the European.
      Want to do the switch? (i.e. I will send you my adapter, which is useless here, and you send me your European)
