Looks pretty neat. Although it can maintain a charge for up to a year, how well will it hold the charge in the cold? That's the issue with all these booster packs - you want to leave them in the car for when they are needed, but any battery depletes rapidly in -30 weather. Or is this one any different?
I was interested in buying the last booster pack advertised on autos.ca - I think it was the Noco booster pack - and it seemed to get great ratings from amazon. Until I read through more of the reviews - most of the ratings were from customers that had been given (free) the booster pack by the company, and then who posted glowing reviews. Customers who actually PAID for the product weren't nearly as impressed, noting that the booster had failed to hold a charge well, and often simply could not boost a V6 or V8 engine (thought it was claimed to boost up to 6.0L V8s). I ended up getting a Clore ES5000 booster from NAPA instead - it's an absolute beast (18 lbs), but I wanted something heavy duty for the 3/4 tonne truck and that would last for years. These mini boosters might do the trick, but I just didn't want to risk it this time.
