Good product but faulty after 3 months
James on 14/04/2017 5 star rating

First off the item it's self is a great piece of kit with instant results once fitted. The multiple battery connections makes it so easy to connect multiple amps and any other 12v electrical items. The only issues is that the instructions (or lack of) is terrible! You have to connect a remote wire to the tiny screw on the side of the battery (nothing states this so rang car audio centre and they helped me out). I have unfortunately had this go faulty after only 3 months usage (hopefully just unlucky as its just the power cap side) as the screen no longer lights up but the battery side of it still works perfectly. I'm sure car audio centre will help as they always do. Definitely recommend to people wanting more power from their system.

Optima? Not anymore...
bassnut on 02/02/2010 5 star rating

I was going to purchase an Optima battery to fit as a 2nd battery and prevent my system sagging. Had a good look around and found them to be coming in at �200 when I noticed the Inphase Battery Cap for just �50 more. I did some research and found that caps were better for quickly releasing energy for big installs like mine but batteries were better for continous power-so this offered the best of both worlds, for a fraction of the price-10farad caps come in at �250+ on their own. So i ordered one in and fitted it in my spare wheel well. I was impressed by the number of connection configurations and the ease of use. Sound wise its: Cleaned up bass, much more dynamic, greater impact and deeper lows. Stopped my full range amp from cutting out whebn big bass kicks in Stopped my full range amp from clipping Given me cleaner mids and tops!(DIDN'T THINK IT WOULD AFFECT THESE MUCH!)SORRY CAPS! Also doesn't weigh as much as a 2nd battery and caps-not much difference to me but you racers might like to know!

  • Question: 16 February 2017
    Car: Audi A4 - 2002-2006


    Does this need to have a battery isolator so I don't get battery drain from the main battery?


    We recommend you have trip fuse blocks at both ends between the battery and power cap, no really for battery brain but more for safety purposes.
