Look at this on eBay http://www.ebay.co.uk/itm/152258591561 it's only a cheap ebay piece mate. I cba spending any more cash to check something I bought to check something if that makes sense. That maximum draw factoring in about a 6% driver loss is about right if I was understanding what I was taught correctly. I'm an absolute noob with electronics just winged it lolVerify the accuracy of your voltmeter/ammeter with a good multimeter. I've got a handful of these displays that are off by 100% or more (they read double the actual current). They have little adjustment pots, but they only affect the reading by about 20%.
Edit: Now that I see the display lit up, its quite different from the ones I have. Can you link to a source on that little bugger?
