lvflyer's insistence on need for frequent battery charging sounds odd as if there he has a anomalous current draw or a damaged battery. This is not typical for TW owners.
USB port's transformers have a minor current draw but not enough to draw down even a cheap battery overnight.
The SAE plug styles depicted by original poster are available with different gauge wiring up to 10 gauge for some serious current draw. I route mine up to instrument cluster for dry accessibility and easy phone/camera re-charging. I use mine to pull power out rather than feed power into the bike since LiPo4 batteries hold charge for months and years w/o need for re-charging. Other than pre-charging new batteries before installation my charger gather dust. My 2 bikes have seen the charger perhaps a total of 3 times in 27 combined years of TW ownership.
Typical use is to run an air compressor but can jump-start other bikes and have used it once to trickle charge dead battery in my van.
I believe the term "battery tender" is a registered trademark of the Deltron Company, and they slap the name Battery Tender on a wide range of over 70 of their products including several battery charging devices. 2-pole SAE plug is a more unique identifier for what is shown in post #1.
