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

I use these batteries in my bishop machines with no issues.

I do permanent makeup and paramedical tattoos. I purchased a new, smaller machine specifically for the face (Dragonhawk Mast Tour) and tried to purchase a well known “shorty” wireless battery to go with the machine. What arrived had the incorrect plug for my machine, so I had to return it and literally everywhere was out of the version I needed. Scrambling to find a replacement and quickly, I found this battery and ordered it, fully planning on sending it back.I was shocked when I did my first practice set of brows with the new machine and this lovely battery! The low volts are perfection, I needed that 4-5 range my other machine doesn’t have, and I completed a brow in about 10 minutes on silicone, all while testing speeds with the battery.It is a little wider than I had hoped, but it has gone through 8 hours of practice and I have only gone down to half a battery. So the size is worth the capacity! I have done multiple clients in the same day without having to charge and it’s working beautifully. I love the gold color, though I wish they had the same metallic blue as my machine, I would buy another one if they did!The only “con”, if there is one… is just where the charging port is. I wish it was on the back of the battery so I could keep this attached to my machine during charging. But honestly that doesn’t bother me that much.I was worried about the quality because of the price but it’s better than I anticipated! Looking forward to hundreds of hours of use!

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 had this battery for a year now in a professional setting, I have never had any issues with it! Works great, lasts long. Still going strong 1 year later!

Battery will not charge, I contacted the company to ask for help and they told me their product only works with the charger they send which is not a thing that’s possible, it’s a normal type c port lol. After telling them my issues with their defective device they told me to just go buy another one. Will not buy from them again.

Ive only had it a month, and realistically this is an item, that should be reviewed a year later. So far it works just as good as my $300 critical batteries and is actual aluminum and not all plastic that breaks when dropped. Yes, Ive dropped this twice now and it is still just fine other than a light scuff on the edge. If this lasts a year like my Critical ones usually do, then its the only brand I will be purchasing from now on. As it is insane to charge $300 for something that can be sold for $39.95. Dont get me wrong, I typically prefer buying American made, even if it costs twice as much. But to cost 12 times as much. That is just greed and insanity. (Dont quote me yet, as I havnt used this for a year yet, because if it only lasts a couple months, then I will go back to Critical which last a year at 10 hours a day 5 days a week.)

Little heavy and noisy.

Great compact size, long battery life, it’s just too loose. It spins around and even comes out of the connection just enough for the machine to not run properly. That’s with my machine wrapped
