LightningBolt Battery Packs

I'm one of those unlucky FK product situations. Bought it through another supplier, followed charging instructions, looked good, turned it off and placed it in drawer for later use. A week later the battery was dead. So I re-charged it, same thing, and then a third time same thing. Contacted FK, went through a hard resetting process, no luck. Sent it in to FK headquarters, got it back (on their dime luckily) with a completely changed battery. Guess what...same issue, battery doesn't hold a charge. I'll be contacting FK again but at this point months into not being able to use this very expensive product I'd warn other buyers to avoid this same possible lemon situation. (Still LOVE my Xion, but sticking to the cord for now I guess). *This review is based on the FK product and does not reflect the amazing service I receive from Eikon :)

This product is great i bought it for my axys Valhalla and it fits like a glove. The charging is insanely fast. But at. 4.2mm stroke with the Valhalla lining anything for me i would run my critical atom x at about 11.2 to maybe 12 volts which i find is normal voltage with a fast hand speed ..from my experience with the lightning bolt it only lasts about 3 hours running at 11.5 to 12. Mind you i was able to tattoo a lot faster not having a cord attached to me getting tangled around my chair.. but if you run your pen machines in the 11 to 12 volt range i would strongly suggest grabbing 2 of these especially for 6 hours long sessions. I ran a voltage output test on the lightning bolt and to my critical atom x . The voltages are accurate When above the 15 to 39% charge i was receiving less power when below. It’s a great little power supply for what it is although definitely could be improved on down the road cant wait to see what the Gen 2 can do !
