Overall, 6 different models of a very similar charger… There seem to be minor discrepancies in size and weight, in addition to a couple of design tweaks. Here’s a comparison based on the FCC filings, which aren’t always accurate:
PowerWave 7.5 Pad (White)
Size: 110 * 110 * 18 mm
Weight: 115g
PowerWave Evo Pad
Size: 110 * 110 * 18 mm
Weight: 99g
PowerWave 7.5 Pad (Black)
Size: 110 * 110 * 12 mm
Weight: 95g

My initial reaction is far too many variations of virtually the same thing. Very confusing for consumers. Pick one and stick with it for awhile, Anker!
