A very worthwhile accessory

September 15, 2013
The charger allows you to charge a battery for your RX100 in 90 minutes, outside the camera, instead of tying up the camera while changing the battery in the camera with the OEM charger supplied with the camera. It also is strong enough to run the camera and comes with USB output as well. It's bundled with a battery which makes it a great deal. I gave only 4stars for design, be ause you have to carefully seat the battery in the charger to make sure the contacts line up. If you have done it right , the charging light comes on, then multiple green lights tell you what fraction of the charging is completed.
