Wireless Tattoo Battery Pack, Rechargeable Cordless Tattoo Power Supply Portable RCA Lithium Battery Pack 1500mAh Capacity with LED Digital Display for Tattoo Pen Rotary Tattoo Machine WB11-A

Works as advertised. Would definitely recommend 👍

Great long last battery to replace my old battery that kept dying while I was tattooing. Definitely worth the money and it’s light weight and fits my tattoo machine. the power supply is the best thing about this battery!

Fit perfect

Why did you pick this product vs others?: This wireless powersupply is a great bang for your buck, it's relatively simple to use and has a timer feature that I love. Mine came fully charges and ready to go which was wonderful for someone impatient like myself. Ease of use: This thing is ridiculously easy to use just plus it into your rotary pen machine and hold the power button to turn it on. You can then change youre voltage to whatever you need for your setup and press the power again to start. Once started it has a timer function that can pause so it can tell you how long you've been working on a piece. Absolutely love it

This battery works just fine. It does however, look a little cheap. The body looks like plastic, as does the screen window, and the fit and finish is loose (small openings where parts are joined). The buttons are very small and have to be mashed quite hard to activate them, but they do work, and they click when pressed for a tactile feel. It has a "dotwork" mode, which could be a useful feature to some, but not something I'd ever use. The instructions do not mention how to reset the timer (Apparently, double pressing the power button, or holding the power button while pressing voltage+ will reset the timer). It seems to last between 3-5 hours depending on voltage, which is decent I guess, but I do usually 4 hour sessions often so I don't want to go in with this battery unless it's a smaller tattoo, or a shorter session. It does charge very quickly, and fits all my pens well. Pros: Very light and comfortable even on longer pens. Charges fast. Dotwork mode available. Low cost. Fits and matches both my wormhole machines perfectly, as well as my other pens. Cons: short/average battery life. Small stiff buttons are hard to activate, especially for larger fingers (I must brace the side of the battery when pressing buttons. If I try to hold the machine and press buttons it will strain/flex the rca jacks on battery and machine).

Wide range of voltage on this one, love the way you can change it and the led screen is nice to have. Fits almost any model of wormhole pens. The battery last longer than most as well with it being as cheap as it is. Good quality overall.

Stopped working after a months of using it

Really good product. Ive been tattooing for 17 years and this battery pack. was bought for my son who was replacing his FK iron battery. He loved it. Stays charged a-lot longer. Cant beat the price.

Parece un complemento original de mis máquinas (pues tengo dos) pero lo que me impresiona más es que aun me aguanta la batería desde la primera carga, mucho mas q las baterías originales. Muy practica y fácil de usar. Muy recomendada. Saludos
