Lithium Ion Battery Pack - 3.7V 6600mAh

I just installed this battery in my wall-mounted SimpleHuman lighted mirror. It arrived fully charged and was so simple to install. I did need the help of a YouTube video with re-installing the on/off button correctly, but other than that it was pretty darn simple I've had the mirror for several years and like it a lot and did not want to have to pay hundreds for a new one, assuming I could even find another one now. The battery was exactly like the original. I am ordering a second one for future use.

I build a weather station DYI project and needed to find a easy way to power it. I build a little box with a Solar Cell charger and glued it on the box. So this battery lasts about a week with a solar panel. It sits outside in the heat during the day and cold at night. So far its lasted a year and still going strong. Well-constructed. Worth the price for your DIY project. 6600mah is a lot of power for the money.

Second time I bought this for mirror. First one lasted 4 years, so not the greatest quality battery but what you going to do, cheap enough to replace every so often.

I bought this for my simple human makeup mirror. My last one barley worked with it plugged in. So got this to try out to avoid spending $300 on a new mirror.I am happy to say this worked perfectly and I have yet to even charge the new battery from the initial charge and that one change has lasted over two months now. Curious to when I will get the indicator light for me to plug it in to charge.

If you have a Simple Human lighted mirror, this is an exact replacement. Right size, right length wires, right connector. I saved a chunk of cash doing the replacement. But I was worried about the input port on the mirror being loose. The seller included a spare port at no cost, and without being asked! I order a lot from Amazon, and it's usually fine. But this product/seller totally exceeded my expectations. Buy without worry.

This is the second Adafruit lithium ion battery pack I've purchased for my "simplehuman" brand magnifying makeup mirror. The first one was almost four years ago! Yes - it lasted that long (!) but this past month finally gave out. It works great, recharges easily and I certainly got my money's worth from the first so I'm hopeful this pack will last just as long. Great buy!

Replaced the battery on a vanity mirror whose battery worked well for may years and cycles. The replacement battery won't recharge. Whatever electricity it had stored on it when it got here was all it was worth. Extremely disappointed.

After about 5 years, my wife's Simplehuman sensor-activated makeup mirror was generally failing to light, even when plugged in. Suspecting the battery was the culprit, I took the base off and removed the battery. I typed it's model # into google and sure enough landed on this product listing (Despite the original saying "Great Power" and this being Adafruit, I can confirm they are basically identical.Replacement just involved:1) Removing the 2 gray rubber plugs in the base of the mirror and unscrewing the 2 screws under them to take the bottom off the base2) Unplug the old battery from the circuit board on the mirror.3) Remove 4 screws from battery housing to free the old battery.Reverse this process to install the new battery.In my opinion, given the relative ease of replacement, Simplehuman should really sell these batteries with instructions as a supported user replaceable item. I worry how many people wound up throwing out a nearly $200 mirror when a $35 battery likely would have gotten it working again.
