Price OK, charger good battery is for a ton

Sounds not bad and it's worth a try.

The charger is OK, well made and works.

I note no appreciable loss of charging time for the original as well as replacement batteries.
Thus, the charging current seems to be similar to the original battery charger.

Also 'on' the charger probably after full charging of the batteries from, where it is probably due to the battery's internal electronics.

As far as price / performance Technically 5 stars for the charger.

The supplied battery (850mAh VHBW) gets exactly 0 stars, although the VHBW battery can be loaded even with the original charger (!).

Both the original and the NoName charger allows the VHBW battery but do not bring more than 50 shots ... at least not with the E-M5 ---> scrap.

Overall, 3 stars
