  1. Cool. I just found out that the LG TechTop wireless charger is actually 12v. So you can alternately install a Boat Outfitters Qi phone holder by simply cutting off the “wall wart” and wiring it direct to 12v.

    Speaking of Battery Chargers what about this being on your boat

  3. Wireless inductive charging is certainly convenient, and 70% efficiency (seen in Qi’s specs) is probably reasonable.
    These devices use 100-200 kHz energy to couple to the device, presumably generated by an inverter in the “transmitter” pad – has anyone tested them to see if they radiate at higher RF frequencies? I would be surprised if they didn’t, and the HF end of the spectrum would be where I would expect to find them (kinda like I find all sorts of radiated noises from switching-mode DC marine battery chargers on HF).
    Jim, while cruisers already have an inverter, I doubt it works from a 350-450 volt DC source..:-)
