US Kindle Fire- charging help.

KxMx

Hi folks, last Christmas I was lucky enough to be sent a Kindle Fire HD from my Dad in the US, this model as far as I can tell.

Been using the USB charger via PC or netbook but it is so slow, 10% an hour if you're not using it!

Picked up this standard US to UK adapter plug, but the Kindle Fire plug supplied with the tablet is small and square. So while the pins fitted it was too small and the wrong shape to click into place and stay there.

I thought this might be an option, simply attach to my existing USB cable, however the V spec matches but the A does not (mine is 0.15 A/ 1A) if I read off the plug.

Anybody have any ideas or do I need to persevere with the USB charging?

Why not just buy a UK Kindle charger, cheap enough on ebay.

Any mains plug with a usb output should work, as supplied with most current smartphones, iphones etc, then use your own usb cable as you've already suggested. It won't be as fast as the Amazon one, which seems steep at £17.99, but will be faster than a computer usb port .

If your computer has USB3 connections or a specified "high power" socket (some motherboards have a specific pair of ports that are 1amp rather than 500ma for this sort of thing), use them for faster charging
You'd probably need to check your PC's documentation for the fast charge ports, but IIRC several of the big board manufacturers were putting them if for a few years (I think it was Asus, Gigabyte and MSI on selected models).

Otherwise as has been said any usb mains adaptor, although look for one with a 1amp or higher output on the USB for faster charging, I think there are some that will go to 1.5a or even 2amp.

The cheap adaptors are usually about 500-1000ma, the official Kindle fast charge adaptor (I think it's black) branded by Amazon is about £18 and supplies something like 1.9amp (so nearly 4 times faster than standard usb for charging).

Many thanks for the replies so far.
As it came from the US i've been wary of buying just anything for it. But am wondering now if all Kindles are made the same and the power plugs added once destination has been sorted.
Certainly doesn't seem like it's one of those tricky US appliances to convert.

My sister (from the US) has recently stayed with me. She charged her US purchased Kindle using my UK purchased Kindle charger just fine.

Ones the input amps the other is the output amps.

Amps = voltage divided by watts. 0.15A max = a max of 36 watts by the charger. Where the output is 1amp @ 5 volts?

USB is slow because it only puts out 0.5A. I have a wireless charger for my phone and its the same 0.5A where the plug is over 1 amp.

So twice as long to charge if i use the wireless charging.

No.

Amps = watts divided by volts.

Therefore a 1 amp charger at 5 volts can supply 5 watts.
