Since I have a K75 as well an an LT, I review the posts on K75's in Yahoo Groups.
Thought this might be interesting to all as well a gobs of good information on the website below . . .

I have finished my extensive testing of 4 versions of DIN adaptors to USB connectors; same for wired versions.
Not easy to find good reliable ones.
Here is my report on the testing, abbreviated (I tested for temperature, output, regulation, and some other things):
DIN PLUG (or WIRES) TO USB POWER ADAPTORS: These are difficult to find. Various versions are available from ONLY ONE company, AFAIK
, that are RELIABLE....and well-made. All connect to your bike's electrical system, either to the battery, or to the system after the ignition switch, or simply plug into the DIN jack on your bike. These adaptors I recommend are NOT cheap cigarette lighter socket plugs but quality Hella-DIN types, that grip well too. All have 5 volt USB type outputs. Single and dual versions, either with 2.1 or 3.3 ampere ratings for output.
NOTE! These items have a tiny current drain when plugged-into your bike. Thus, if you intend to leave them connected all the time, I suggest you wire them into the bike so power is ON to the adaptor only when the ignition switch is ON.
I have thoroughly tested a number of these. Both 3.3 ampere and 2.1 ampere versions have a no-load drain of about 0.006 to 0.007 ampere. The standard 5 volt USB output is solid, well-regulated, and was tested between 11 and 15 volts input at the DIN plug.
BurnsMoto.com seems to be the only source I found in the USA.
Product is made in Taiwan.
Cliff-top.co is the maker, and has some models that are not seemingly available in the USA, but BurnsMoto has what you likely need.
