Speaker 1: Today we're taking a look at a trailer break-away kit battery charger. Now, this unit this is from Hopkins that replaces the battery charger, and it's designed specifically for trailer break-away kits. The black wire on the unit is the wire that would get connected to the vehicle battery to get the charge, the red wire is the wire that gets connected to the battery in the break-away kit on the trailer, and the blue wire is the wire that gets connected to the actual break-away switch. That's gonna do it for today's look at the trailer break-away kit battery charger.
Average Customer Rating: 4.8 out of 5 stars (49 Customer Reviews)
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
Have not installed the charger yet, however it appears to be of good quality
Works great! Easy install!
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.
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.
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.
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. ;)
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
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.
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.
Installed easily with instructions provided.
GREAT SERVICE AND SUPER PRICE. THANKS ETRAILER
Inexpensive solution to ensure your battery doesn't overcharge.
Excellent experience and communication, great product and instructions
Still working great !!
