But let’s go deeper.
When people ask “which lasts longer?”, it can mean two things:
How many times it can charge your phone per full power bank charge
How many years before the battery degrades
Both are rated at 20,000mAh, but usable capacity is around 12,000–14,000mAh after voltage conversion.
Anker PowerCore 20000
~4 to 5 full charges
Romoss 20000mAh
~4 to 5 full charges
In terms of raw capacity, they are nearly identical.
📌 Tie in single-charge capacity
Here’s where differences appear.
