Robust and highly efficient charger.

To begin, let me say that I withdraw a star for the price that is too high in my opinion 5 euros but justified by these two criteria that will interest a lot and that is not found in other manufacturers: it is designed to withstand shocks and some falls, and is guaranteed ... 7 years!
Comes with correct size transformer, the charger is a little imposing but very light and stable.
It has a smoked plastic cover.
There is a LED independent of load status for each of the 4 batteries.
Accuracy: the charging time indicated hour is for 2 battery capacity of 1300mA AA format.
To charge 4 AA batteries Philips brand (1500mA): the charger has performed the work in around 1:20 which is very satisfying.
It can load both 4 AA size batteries, AAA, D and C ... BUT 1 9 volt battery at a time IMPORTANT ACCURACY.
This is the only disappointment for me because I use more than one.
For the rest, the charger has various protections against overvoltage and short circuit, and stops charging when it detects that the batteries are fully charged.
Given its relatively low weight and small size of the transformer, it can be taken in baggage.
Overall, there appears to be a very good charger, plus a guarantee of 7 years, which is an asset and can justify its price for many consumers.
