Works perfectly as advertised!

It works great. I have use this one for my LG innotek 2 channels.

Great product. Lots of connecting options.

this product works great

Works well for daily routine. Don't forget there is a small switch to turn the battery on/off. If it is at "off", it would not do anything. I was almost returning this because of the switch was at "off".

My current unit is working well. Definitely prefer this over the power magic battery pack which would not consistently charge. I have given three stars because the first unit i received began to smoke immediately after installing. All wiring was done properly and i can confirm that the new unit i received from black box my car is working fabulously with healthy charge times. I would always buy from this retailer for any future purchases. They are great with returns and are even available on Saturdays over the phone!

Good but causes interference on FM radio and blocks DAB completely when plugged in.

Brilliant, wish I'd have bought the expansion battery along with this at the same time

Good one

Product works as it is supposed to. I was hesitant at first, but ended up buying this unit. As I wanted something with good quality.Cons...- Wish there was an option to disable power on/power off beeping tones, without having to open up the unit and disable it.- Apart from the x1 red charging led, and x1 green charged led. There should have been at least x4 led's for how much juice you have left on the device. So you get a better understanding of where the power is.- This unit I think is VERY expensive, for the amount of juice you are getting. Should have been about $100 less.Pros...- For me personally I don't mind the beeping. This way I know the unit is working everytime I start/shut off my SUV.- This unit is reliable. I have this unit hardwired into my SUV. And it does charge everytime I start my vehicle. And when I shut my vehicle off, it does take over instantly. With no interruption to my dual dash camera set-up.

Easy to install. I satisfy with the product but the price here is way to high. Almost $100 more than country of origin.
