Trailer battery to charge phones, etc...

Post by echinus1988 » Thu Jan 03, 2019 5:45 am



know this has been somewhat addressed. In fact, WingAdmin has set it up in his trailer to work off the bike or 120V.

My question is, how?

I can do the work but I'm not exactly strong on electrical stuff. I'm figuring power via my wiring from the bike to the trailer to allow the battery to charge while I'm riding. An isolator to keep from discharging my motorcycle battery. But hooking up to 120V on top of that (if I understood it correctly) is something I'm a bit nervous on.

So, my question is, how to best wire it in so it charges from 120V when I am plugged in or charge from the bike while I'm riding. Or possibly putting a small solar panel on so it can charge as long as I have sunlight but more like off the bike and 120V. I do understand that an AGM battery is no leak and no fumes. And I do have the connectors and the tool for Anderson Powerwerx to make the wires and attachments.

Any help would be appreciated.

Thank you and Please Always Ride Safe!

In my experience,

just using a Car Cig plugin charger to a cellphone w/o the engine running and giving you 14.x volts to the little plugin module, results in a very slow recharge to the phone, if any at all.

it will work, but it won't be a Fast Charge like when the charger module can see a full 14.3 volts

IF the trailer's battery is being recharged from the bike while you are riding, then the 12v to 5v USB mini-chargers should do a pretty good job.

But, be aware, that all cellphone chargers are not alike, even when you have 5 of the same exact brand name and model in your hands...... it seems that the Asian folks just love to slap a decal over something and claim it is the OEM factory version...

I have a box full of useless USB cellphone chargers, and just gave up on them.
I now only use Anker brand charger modules, at least theirs works.

What I use is a portable battery jump starter, can be charged while riding thru a power port on bike. Can also be charge from a standard 120v outlet. Will jump start bike or charge any device thru USB ports

I don't have this exact unit mine has a little more output but could not find it online right now. There are many to choose from at a wide range of prices. But mine has worked well for 4 years now.

Yep, I see what you have. I have a small jumper unit like that but I also carry a 26000 Ma that can charge 3 units at one time.

I didn't mention that I have lights to add also. I feel the battery would be a nice addition for the lights and to charge items. Might get a big enough one for my 12V electric blanket! I should have mentioned the lights.

So I'll carry my charger like you suggested but I still would like to add a battery to run the lights.

I think it's simpler than I am thinking. Just run a line from my 120V shore outlet to a small charger and then one from my 12V on the bike back to the battery.

Thank you for the input.

Ride safe!
