This battery charger pulls just enough power from your vehicle when your trailer is hooked up to make sure your breakaway battery stays charged and ready to go in case a disconnect ever occurs. Compact enough to fit inside your breakaway battery box.

Specs:
Note: A breakaway system is required by law in most states for trailers that are equipped with electric brakes and have a GTW of at least 3,000 lbs.

speedy shipping and works GREAT, until next time thank you!!!!!!!!!!!!!!
recieved in good shape and what i wanted thks
It gives me peace of mind knowing that my trailer battery is being charged while I'm driving down the road on a trip since the trailer/battery sits most of the year. This item was easy to install. The harder part was the van wiring, connecting a wire to the van's trailer connection so that the charger thing could work.
Great little electric brake battery charger. Easy install. Fast shipping and a great price. Thanks etrailer. Definitely buy from etrailer again.
Great product for horse trailers like mine whose manufacturer was too cheap to include. Easy install and wires are marked where they go. Fairly priced too.

Product working perfectly after 1 year. No complaints.
A simple low cost solution that is easy to install. Installation took about 20min. In my opinion every trailer from the factory should have these pre- installed but many don't and without one the small breakaway battery will charge at too high a rate and probably overcharge, both of which can shorten the life of the battery.
great little battery charger fit into breakaway box just fine. I use it on a double axle utility trailer. It will keep trailer break away battery charged up
Still working great - just checked battery voltage after being parked a few days: 12.90 on the SLA alarm-type battery, so it's certainly working.
Always forgot to maintain, or even check the last battery - have no idea when it actually died. Wiring in this regulator ensures that it will have a much better chance of actually working IF I ever need it to. Lets hope not. ;)
I bought TR20048, and after about 2 years the charging circuit started malfunctioning. There are no replacement parts for TR20048. So I removed the original circuitry from the TR20048 and replaced it with 20011. 20011 does not have LED indicator lights, but it charges the battery without overcharging and is very inexpensive.
Easy installation. Durable connectors. Has worked great. Would highly recommend this product.
It took about 5 minutes to install this charger. I can't understand why trailers don't come with these from the manufacturer.
Etrailer is great, and we'll be doing more business in the future. I have a few trailers, and I can't imagine needing anything that Etrailer doesn't carry.
I like your website its got everything I need for my trailers and will come back and order again. Couldn't find any of these products locally found everything on etrailer.com. Great site.
simple, sealed, haven't used it yet put pretty sure its just a few diodes molded in plastic with pigtails to prevent back-draining and overcharge, seems pretty robust
Does not come with any instructions, so get the wire coding off the internet here.
Tiny, will be easy to mount in the battery box.
I have installed the battery charger, and it seems to be working fine. I was impressed with the quick delivery and good packing.
GREAT SERVICE AND SUPER PRICE. THANKS ETRAILER
