Samsung Watch 4 Classic 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.

I've only used it for a short while but so far I have nothing negative to say about it. It charged my Samsung Note 5 from very low (4%) to full in about an hour and there were still 3 lights remaining (about 75% capacity). It's a little heavier than I expected or would prefer but that's not too big a deal. The attached cords are a nice touch and there's also no need to turn it on. Just plug it into your device and it starts charging. Easy Peasy!

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.
