What adaptor do I need for this charger?

Hi,

 I bought a couple of these: http://www.ebay.com.au/itm/5V-Mobile-Power-Supply-USB-Battery-Charger-18...

and the seller told me not to use a 9V 2A adaptor, which one would be best or provide quickest charging (I guess that would be at the expense of cell life?)

 

Thanks

Can't see why the 9V 2A adapter wouldn't work. The device looks kinda home-made though.

 

If its maximum output is 5V 2A then a 9V 1.1A adapter would be adequate but if a 9V 2A one is what you have there shouldn't be a problem - the charger will just draw what it needs, not what the adapter is capable of supplying.

 

 

I think...

 

The numbers from my light tests are always to be found here.
