The secret to super cheap Chinese electronics, is assuming the max rating is not real.frater secessus said:Maybe base it on something like this?
Best case it gets real hot run up to anywhere near the published max rating.
Worst case they meant "for 5min at a time" and you get to see it release the magic smoke.
Nice thing about eBay is try a few, claim refund on the ones that fail, have the #2 around as a spare.
But always report test results here!
