Wireless Cell Phone Charger - (Under construction). |
|
|
It is nice to have a convenient location to drop my cell phone into where it is secure, can stay dry, is within audible and physical reach of the cockpit. I can charge it in the holder and I can see it to remind myself to I take it home at the end of the day. I recently tested the how much magnetic interference an Apple wireless charger has. My concern was magnetic interference to the steering compass in the cockpit. Not that I use a compass all that much on a lake but why create a problem. The people at the Apple Store were quite surprised when I pulled out my hand compass. The magnetic field extends out ~12" without an iPhone resting on it and ~2" with an iPhone on it. If the charger is installed 5' away from the steering compass, on the opposite of the cabin, there won't be any interference to the compass or the Tiller Pilot flux gate compass.
DRY & CONVENIENT - Location is everything. The holder will be installed on the starboard side of the cabin, away from rain and within convenient reach of the cockpit. Just drop it in and let the iPhone charge, then get back to the helm. There will be 2 holes in the bottom of the case so it passes the most sound from the speakers. It would be nice to extend this to the cockpit but then a blue tooth ear bud would do that as well. CHARGE - The 1/4" thick charger will be imbedded in the back of the holder creating a flush surface to protect both the charger and the iPhone. The USB charger already has a power switch (breaker 10) for when charging is not required. To achieve optimum charge performance requires a 20W USB charger. VISIBILITY - The iPhone will show at the top of this holder to reveal, "I'm here!". This should be enough to remind to grab it when I leave the Panache! As ridiculous as this sounds I`m tired of driving back to Panache to pick up my cell phone. _______________________________________________________ |

SECURE - At the back of this holder I will imbed
the Apple 20W wireless charger that holds the iPhone magnetically to ensure maximum charge current and prevent movement. Eliminating vibration and shock is hugely important
for electronics.
