Tattoo Power Supply - Kuark Mini Wireless Portable RCA Tattoo 2400mAh Lithium Battery Pack with LED Digital Display for Rotary Tattoo Machine

I've been using this battery 3-4 days a week for 9 months and it's definitely on par with the Critical batteries. I use a Bishop Shader Wand at 5-7 volts and can still get around 8 hours of tattooing in, at this point with my Critical batteries I'd be getting about 6 hours. I don't experience any loss of power as I drain the battery's charge and it's weight doesn't feel like it's an issue. As much as I don't love the idea of Amazon selling tattoo equipment, it's hard to beat a solid battery at this price versus what Critical charges.

I waiting a good 2 weeks before I wrote a review for this battery pack. First let me say, as someone who is used to spending good money on batteries- critical and bishop, I was a little bit sketch about trying this pack. I run a bishop wand and an fk irons xion amongst other machines. This battery is slightly heavier than both the bishop battery and the critical shorty. I believe it's even heavier than the full size critical, but not by much. With that being said, I really don't care because the batery life of this battery, actually blew me away. I got about 14hrs of tattooing out of it. It fit snug on the RCAs of both machines. The digital display is clear and easy to read and having a clock to keep track of time is a nifty upgrade. So far, I have nothing bad to say about this battery. It's a good alternative to buying these $200-250 battery packs I plan on buying another one for back up real soon. Kudos to this unit Five stars k⭐️⭐️⭐️⭐️⭐️

I’m a Tattooer of 24 years professionally. I bought my first ambition battery in 2022. After 4 years of continuous daily work, this week, it has started to run out of power after 4 hrs. It has been used everyday since I bought it. I have bought quite a few other brands. Even some of the more “critical” kinds…. They don’t hold a flame to these. These are worth every penny. I have three of these batteries now. Two larger and one shorty. They keep my business running smoothly without power drop. Keep it up guys, you’ve nailed the battery game.

Great potential but only worked for once use before never being able to charge. Tried multiple chargers and no response. Out of luck with a dud and no return window. Lasts for a long time if you get one that actually works. :(

Last me up to 10 hours, consistent power no issues definitely worth buying
