V250
Posted by Dexter YarzaThe main reason that I purchased the V250 is because, to the best of my knowledge, it has the highest capacity of any power bank/battery pack in a relatively compact profile. Also, it can recharge my 2012 15" MBP with ease due to Voltaic's Magsafe 1 adapter. All in all, I am quite pleased with it's performance as it is able to charge up my MBP for up to three times. The only reason that I gave it four stars is because it's display is too simplistic and, at the very least, should show a percentage of battery charge and PD port would be better with a 60W or 100W bidirectional(input/output) instead of the current 45W.

250 Volt Battery
Posted by Cutie PieIm disabled. I found when I have to go to the hospital that wall plugs are inconvenient. Either the usb cables are too short to reach the wall, or the outlets are underneath the bed, where I can’t reach. So when I found this battery on the Internet, i was amazed. This battery holds 17 phone charges, or 3 tablet charges.
In my own experience, I’ve gone two days using this battery without physically recharging it into the wall! The only drawback is that it’s too powerful to carry on an airplane. I use the smaller v88 battery for traveling. Thank you Voltaic Systems for this innovative battery! -
I like this product! I’ve used their v88 battery before, but it didn’t have a USB-C port. The 250 does. It Jasso much more energy that I can go two full days without charging the battery! However, other people may differ. The only drawback I see is
Posted by Energy SeekerBattery IS kind of bulky.
