Hawink Wireless Mini Tattoo Battery Dedicated 3.7V Lithium Battery 1600mAh, 3 Hours Continuous Power Supply P199-DC

got here fast. works perfectly. definitely recommend.

The media could not be loaded. Purchased with intention of having an extra battery “in case”. Got this one even though not many comments. Was I surprised when I used it for several days. Works great and long lasting battery. Has five voltage settings from 5.0 to 11.0 Using this one as my primary now.

This battery works great, already ordered a second one for my other machine. Charge lasts just as long as the more expensive batteries. The only thing you may not like is not having the ability to dial in precise voltage, they have set voltages but I haven’t seen it as an issue.

Drained the battery to fast

Long story short, I have multiple tools for services and procedures that I offer at my beauty studio. I had gotten the purple rotary gun/pen on a whim, and I loved it, but I immediately realized I needed this to make it all function properly. It has become my favorite, go-to system for providing medical/beauty tattooing as well as scalp micro pigmentation. It is perfect!

The media could not be loaded. So I bought the initial Solong rotary pen set. Love the machine! Surprisingly powerful and had a great battery life. I ordered a second battery to be able to use the wireless pen for multiple tattoos throughout the day. The battery will turn on the pen with no problems, but will not allow a lower setting, when attempted to lower the setting to 5v (lowest setting on the battery) the whole battery just shuts off. Amazon is replacing the battery so I'm happy, but the inconvenience of these cheap batteries does suck bad. You definitely get a better quality item than expected. When it works its excellent, but if I continue to have issues like this its hard to recommend. Quality is not quite there yet, you get what you pay for.

It’s very easy to use. It has a decent battery life, (I always keep two batteries just in case) It doesn’t fit all the way into my machine but still runs without cutting in and out.

Exactly what I ordered. Package well and safely. However my husband got the wrong size. I'm sure it works fine. However, do to getting the wrong size, he's unable to test it. Just double check the machines name and numbers.
