Watch 4 Battery Drain

I used this product because it is less drain on my camera battery

Love it so much, did not experience any noticeable battery drain while sitting.

The drain battery feature is brilliant. It helps maximize the life of your batteries.

This is exactly what I needed. I still haven't managed to drain 1 full battery on a busy shoot.

I like the separate meters for each battery and drain option to get the batteries back to full charge.

You can never have enough juice. You're constantly reviewing off the LCD can drain the battery charge so having a spare is a must.

recommend spare back up battery for cold weather battery drain & about the time you want a shot---the battery is dead.

It is an oscillator. It works. Super portable. Has a little power switch on it so that you don't just drain the battery when not in use.

Super bright light. I like that it automatically goes back to the lower setting so the battery doesnt drain as fast.

I've never had a battery charger that would actually drain the batteries completely before charging them. That's a really good idea for NiMH, since they are supposed to be empty, but their usefulness drops off before they are dead, if you're using them for flash. The display is bright, and always on unless you unplug it, which is what I do. It comes with a car adapter. Excellent investment, very happy that I went with this particular charger, so I could have two sets of batteries at all times. Batteries also charge up quickly, about 4 hours as advertised, with a complete drainage.
