Dragonhawk B1 Cordless Tattoo Battery Power Supply Lightweight Small LCD Display Screen for Tattoo Pen Machine (RCA) 4V-12V 1300mAh

I love dragonhawk brand in all of my tattoo supplies. I use the mast pen and love that it fits in my small hands without issues. I have a hard time holding larger/heavier machines. I was worried this battery pack would add too much weight to remain comfortable for me, but I am pleasantly surprised. I can easily hold this battery and pen for hours without it cramping my small hands, and the battery lasts a decent amount of time as well. I plan to purchase an additional battery to have on hand to swap out to keep one charging at all times. I recommend any Dragonhawk products!

Never had an issue with Dragonhawk. This is surprisingly lightweight but works and feels like it's quality made. It's small, smaller than I'm used to. But as a back up this is great to have. I wouldn't even mind having two of them on hand as a back up. Takes forever to charge

This definitely works as intended, but I wish the battery life lasted longer than two hours as I sometimes tattoo for 4 to 8 at a time. So I had to buy two so that I can have one charging while I use the other, but it is a little irritating to have to switch back-and-forth. it is very consistent, stable, and I love the option to adjust the voltage.

I love all of Dragonhawk's products because, unlike other companies, their tattoo machines are so reliable. This is no exception - this battery power supply is very small but works great - it is compatible with most tattoo machines. It is lightweight and easy to take with you. Most Dragonhawk tattoo kits come with a battery like this but they're usually larger. It's nice having this extra one as a backup - it's so compact that you can easily take with you everywhere.

This review is for the Dragonhawk B1 Wireless Tattoo Battery Power Supply Lightweight Small Lcd Display Screen for Tattoo Pen Machine (RCA) Dragonhawk gear is just a beast. Double awesome.

This battery supply offers my favorite tattoo pen all the extra power I desire to finish a nice size ink job. It’s not only wireless, but gives me 6 to 12 hours of energy. Now that’s true battery life!

I really like that this shows amperage usage and voltage. It uses very light weight materials but it seems quality. Not yet sure how long the battery lasts. The display goes from 3v to 15v. The voltages are dead on accurate until you get up to around 10 volts then they get very inaccurate. At 15v on the display the actual voltage is just 12.65. I even exchanged for a replacement because I thought maybe I got a bad device. Unfortunately, that was not the case, both devices had exactly the same issue so the company must know about this and has not fixed it. Normally it would be one star off but I'm taking two because I believe they are selling a product with a known design defect. All that said, the voltage may not actually matter when using this in practice, to power a tattoo device, if that these case for you, this should work nicely for you.

I only got this for a backup, because you really don't want to be without a battery power supply. It is lightweight but doesn't feel cheap. I haven't used it much, usually for when I want to do a quick touch up. But comforting to know it is a good brand and I have it if I need it.
