I was thinking of buying one of these for my 1993 K75s-http://www.ebay.com.au/itm/381247784887?_trksid=p2055119.m1438.l2649&ssPageName=STRK%3AMEBIDX%3AIT
Can anyone see any problems? I really just want to be able to charge my phone to and from work. Do you think it will put too much drain on alternator, especially now with heated grips on, or would it drain the battery with nothing plugged in? I was going to go straight on to the battery, with a fuse.

A phone charge is a pretty small load, so I'd be very surprised if there was any issue. Typically about 5W. iPad or similar would take about 12W if the output of the USB plug is capable of it. Even that should be fine unless the charging system is dodgy or you have other high power extras running.

Shouldn't drain battery when nothing plugged in, but remove insert to be sure.

Woody, I've never done the calculations but I've been charging phone or camera while travelling on my bikes for years and never had a problem. Go for it.

Cheers

The specs say 3.1amps... at 5V = 15.5w maximun. You could charge 2 phones with watts to spare. Won't be a problem. But don't connect it straight to the battery. Fuse 4 is unused and from fuse 5 you can connect straight into the special equipment conector which has a 15amp fuse.

I'm using a Powerlet PPC-035-DB fused, voltage reduced stretchy cable under the bodywork and appearing at the 'bars to charge my Android with a micro USB plug...



...along with a RAM Mount X-Grip holding the phone tightly using a 1/2" ball mount into an 8mm Allen head screw on a short arm, bluetoothed into my helmet(s) through a Cardo Q1. It's boss.



I can ride all day with a fully charged phone receiving music and directions from GPS. But still I'm lost, just the way I like it.

My K100RS Trike has a port on it.

I did it myself with abit of soldering, and some iffy business.

I simply bought a new cigarette lighter bit and a lighter to USB adapter, and there we go!

I will be re-wiring it into the front side of the fairing when I get out of hospital, but for now, it does a great job running a car stereo.

While the stereo may be tad too much a times, the charger will not even come close to anything that will worry the eleccie bits on the bike, its just too little drain.

Ive gone through a few of these.

I dont like the style of the one you have linked to. I had 2 of them and in both cases water got into them and wrecked them. The cover/seal bit does not work as well as it should.

I have been using this style of USB charger for the last year with no dramas at all. This cover seals very well.

Ive got a K1100 alternator, and all my add-on accessories (stereo, USB charger, driving lights, headlight relay circuits) are wired through an auxiliary fuse holder Ive installed on the other side of the relay box.
