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

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⭐️⭐️⭐️⭐️⭐️

This battery is absolutely amazing. After 3 hours it didn't went down on battery percentage at all. It's not that heavy my hand got used to it pretty quick. It sits in my kwadron tatto gun perfectly,doesn't fall out or disconnect in a process. I bought 2 batteries in case one dies when i have a long session but I don't think I should be afraid of it. Absolutely amazing,for this price it's a steal. BTW arrives fully charged,nice bonus. Thank you,it eased my work so much,no more cords.

Broke just short of a year. Replacement was going to take 2 weeks and I tattoo every day, so I couldn’t wait l. I happened to have a shorty from Critical, but 4 hours is not sufficient on a daily basis. Tried to ask for a refund (if even partial) and allow me to just ship the old one to the California address they provided and they never responded. The voltage increase button started malfunctioning one day out of nowhere. Like from my usual 5.6-6 to TWELVE at once. I luckily was not working on a client when this happened. But imagine if I was?! Bought a full size Critical RCA like I should have the first time. Will not cheap out again.

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.

These are better than some name brands out there! I was happily surprised with the quality! I would suggest every tattooer getting one (or even 2) of these batteries
