Mummy Tattoo Battery Pack Tattoo Power Supply with Digital Oled Screen Display For Rotary Tattoo Pen Machine (black)

This battery is great for the price. I needed something that last more than 3 hours like most of the other wireless batteries. This battery weighs more than my others but I find myself using this one the most. The weight balances nicely and if you're not running at full speed it will easily last you 6 hours. The customer service was fast and friendly, I had to RMA one after a few months as it quit working but they quickly sent out a free replacement within 3 days.

Bought three ... one smelled like burning electricity as soon as I plugged it in and died ... other two work fine tho

I ordered this battery out of desperation one day when my Bishop battery crapped out on me. I was waiting for my Bishop replacement to come but shipping times from most tattoo supply companies right now are insane. I figured I would try this out and worst case scenario just return it if it was awful. I am SHOCKED by how well it works. I use this with my Bishop packer and it works just great. It lasts for hours (fully charged, I'd say 6-7 hours if you run your machine between 7.0-8.2). The layout of the buttons is similar to the Bishop RCA battery and I actually prefer this one now that my new Bishop arrived. I am very happy I gave this one a shot.

I wasn't sure if I could trust the reviews but, for the price, not a huge gamble.I have been using it for about a month now and I've had no issues so far. I had issues with cheaper batteries not putting out accurate power. This one is smooth, accurate and consistent. Also the battery life is great, I've used it for hours on end and barely made a dent.It's well worth the money.

If you have a power outage or are you looking to do some portable tattooing or just some tattooing where it feels more like you're holding a pen this is definitely worth the purchase I was worried that it would add extra weight to make it feel weird like one of the older machines but it balances out quite nice perfect product

This little guy cranks!Been using day in, day out since October with no issues.Last all day for me (6hrs+), I usually tend to run my machines at a lower voltage (5v), which helps the longevity.The digital readout with + and - adjustments is great.Highly recommend!

First, I'm not sure if it matters but I am a beginner and highly mature tattooist. Having said that I did have a few concerns when I bought this. I love my mummy rotary gun so I figured it was worth the risk, and boy was I right. My main concerns were length of time that it would hold a charge and how much it weighed. After charging it fully before using it I've used it for 3 hours straight and it's still 50% full conservativly. As for the weight it's not too heavy to make any negative impact while using it, although it did take a short while to get used to it. I'm not certain this review will be of help to anyone but it's what I was wondering so I hope it does.

Excellent battery, long life, quick to charge and easy to use.
