A very good company to buy from
Great product. Good service and good contact with me.
works
Second one of these I have bought. Worked well but was fried when my alternator went bad. Great timely delivery and price.
Wiring instructions left a lot to be desired
The battery isolator l purchased from you guys is serving me well with no issues.l don't have to worry about my starter battery running down except for unrelated reasons.
Timely delivery arrival, very good packing job, undamaged NEW items arrived due to good customer service. This is definitely a high quality unit. The heat generating epoxy-sealed electronics are protected from overheat by a generous amount of blue-anodized extruded aluminum cooling fins. This is a good value, and it is the reason that I bought 2 of them... One for use, and another for a back-up, in case I have a shorted battery... Keep-up the good work!
The 95 amp isolator is an excellent unit. Used on my RAM 2500 diesel pickup for my pop-top camper, this unit is quite sufficient to keep both my dual truck batteries and dual camper batteries charged by my 160 amp OEM alternator. Quality gear; Highly recommended!

Just put it in and a big different in all things electric on vehicle.
It worked a advertised
In my 75 Dodge van ...works very well,!
Ordered by phone with Gwen and Stacy's help and elected to pickup the battery isolator in Wentzville, Missouri. Price was great and it has a one-year warranty. Within an hour or two they emailed it was ready. Pickup was also quick and professional. Item is an exact replacement for the 25-year-old failed part in terms of form, fit and function. Installed without rewiring or drilling and is working great! This could not have been a better experience!
While it was a challenge to put it in our motorhome, once installed, it works perfectly. It appeared almost identical to the original one I removed on our 1996 Road Trek.
Going to give it a 2500 mile test run t omorrow.
Easy to install and works great.
We always get a great product from Etra iler.
Great selection and very reasonable prices, many with discounts, often cheaper than that big online site. Particularly impressed with customer service when I had a product issue, called me right away and offered replacement item immediately with free UPS return label.
All I can say is that Etrailer ROCKS! Ordered on Tuesday and got it Thursday. The only thing better is if I could’ve picked it up myself!
Thanks Etrailer for fantastic service!
excellent service
Put it in and works great-
