PUrchased this to go with drones from Holy Stone. Product arrived quickly with Prime and the device is a neat way to always have plenty of charged batteries for flying. Each battery provides about 7 minutes of flying time and can be swapped for a new battery in a bout a minute. Charges 4 batteries in about an hour if you use a good cell phone wall wart instead of the USB port on your computer (which seems to take longer.)

A must-have accessory for a great drone

I got this set for my HS110W and it is perfect – exactly what you need to stay up in the air for long periods of time. Each battery gives about 8-10 minutes so buy packs accordingly. This set should give you about 32-40 minutes of airtime. The batteries came as described and work like a charm. You definitely need at least one of these sets if you have a compatible Holy Stone drone (also that is fun to say haha).

it had worked great every time

I must admit that, after reading some of the reviews on this product, I was hesitant about buying it. Seeing there wasn’t many choices I went ahead and made the purchase.

Not worth it, poorly manufactured…

Update March 2017: Finally received a replacement from Holy Stone for this charger, so I have updated to 4 stars as the product works fine if it doesn’t break. Thanks to customer support, though 3 months later.

More fun time (~30 min) of flying a drone with those batteries!

After a few days the charger broke. The USB port like what others have said is very cheap. If you’re not babying it, it will break. Contacted the seller and im still waiting for them to reply. Been 4 days since i emailed them.

Broken micro USB port

Works as intended. I like the adapter for the other plug type to use with other batteries/drones (adapts to hubsan battery for example). The first charger I had started to have a loose connection to the USB cable after a couple of connects/disconnects but holy stone has great customer service a sent a whole new set. Now I just leave the USB cable connected to charger to not damage that end.
