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've been a professional for just over 10 years, and just like the jump from coil to rotary is a big one, as is PS to battery. Its liberating.I was slightly skeptical of these at first but damn, what a great way to spend 60 bucks. I run my Xion at 9 volts with a 3.7 mm stroke lobe. I ran this battery for 6 hours and it was only half depleted. I'm going to buy more.Some dude said this is the Honda of batteries which was the deciding statement when I bought em. He wasnt lying.

I love this battery it has great power and the running time on this is amazing I did a four session & only loss about 20% this battery is great for all wireless rca compatible devices of the tattoo industry I really could use a new one I accidentally lost mine at a convention 🤦🏾‍♂️ but I would tell anyone who wants to start and your on a budget this is better than any top name brand battery on the market 💪🏾

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