I have ordered 3V-24V 3A EU version (Model UM715). I have tested the output current capacity and it cuts the current at 0.5A. So at 1/6th of the advertised value! I have contacted the seller. Seller says "The number of amps varies from country to country" which is obviously incorrect! I have bought the EU version with 3A rating. Current capacity does not depend on anything else. The rating on the brick is 100-240V, 3A output. Obviously my 220V AC is within these limits. I am not satisfied neither with the product nor with the response of the seller.
Not working (dead on arrival) but without external damage. Refunded full amount.
