💬What Redditors Actually Say

What Redditors Say

Best praise vs top criticism for Nitecore NB10000

Best Praise
+58 pts
“A single large power bank will probably take more time to recharge, than say three NB-10000. Also will have less redundancy and be a single point of failure than three NB-10000. Also for group trips three separate NB-10000 will let 3 different people use them (and carry them) than a single power bank. Also for shorter trips maybe only taking one of the NB-10000 is feasible. And one can get 3 wall chargers to parallel charge three NB-10000. In summary, I can understand why there not too many larger powerbanks sold.”

“That doesn’t suprise me. I had 3 or 4 different bum power banks from Nitecore. They get recommended a lot due to the weight stats but you don’t have to look real far to find folks who have had issues with them.”
