I bought this so that I wouldnt' have to keep paying for batteries all the time for my camera. Most battery chargers cost a lot more than this one did (I bought this one for about £12, from Amazon), so it was good to get a deal on it.
The package includes the charger itself, 4 AA batteries and a car adapter, so you can charge your batteries in the car.
The batteries are easy to insert, there are two spring-loaded extensions that spring out. These are so you can charge AAA batteries as well, and they fold away when you're charging AA batteries.
I find that charging batteries doesn't take very much time at all, I just leave them in for a short while and after a short while the red light turns green to show that the charge is complete.
The build of the charger doesn't seem very strong, it feels rather plasticky. However, I haven't had any problems with it so far, and it's held together fine, so i can't say that's a problem at all.
I'd say this charger is worth the price. However, if you want something perfectly reliable you should maybe spend a few extra quid and get an Energizer one or something more expensive.
I picked up this charger a few days ago for £8 with 4 1000mah AAA batteries which seemed like a great price to me for a 'Smart' charger.
In the package I got the charger (quite slim) a standard plug adaptor and a car charger making it ideal to take around with you ensuring you never miss out on a photo perfect moment.
The charger has space for 2 or 4 AA or AAA batteries and has quite a rapid charge time. Here are the charge times quoted by Uniross:
Charging Times: AA 1300mAh : 120 mins, AA 2500mAh : 255mins, AAA 900mAh : 180 mins
It is not the fastest charger around but clearly not the slowest. The main reason why I choose this charger was as it had a charge detection system allowing it to detect how much charge a battery needs until its full. This would be standard you would expect but still many chargers are sold which can possibly over charger batteries if the user is not careful.
After unpacking I plugged it in and started charging 4 AA batteries I had which were rated at 2350mah within 2 hours the green light came on to tell me they were ready for use. Once putting them into my camera to test it stated they were 3/4 full. I found this strange and put them back into the charger. The red light returned on stating they were charging and they charged for a further 30 minutes before the green light gave me the all clear. This time the camera registered them as fully charged.
When charging batteries now I tend to charger them again after the green light comes on as this seems to get them upto full power. It is clear the unit is very cautious of overcharging the batteries so issues the green light in earlier then necessary (in some cases anyway).
Overall this is a great charger and I recommend it to potential buyers its not to expensive and will not overcharge your batteries. Charging times are above average and the included car charger will be beneficial to many.
