20,000 mAh with several output options for $40 at Walmart. Has a 2 Amp USB port (too high for charging 18650's I think) but also a standard plug outlet. The cool thing is that it's about the size of a large dual battery box mod. I wonder if there are any battery chargers with built in power banks? |
Does it have a 510?
To add, I maintain a .5 amp charge to my 18650s. Helps with the life. I don't even think my luc v4 goes to 2A, so I think you're right.
