Understanding powerbank sizes
How many charges does a 10,000mAh Powerbank really give you?
Think a 10,000mAh gives your phone 3 full charges? Not quite.
Its one of the most common assumptions people make. You look at your phone (let’s say it’s a 3,000mAh battery) and assume a 10,000mAh Powerbank should charge it 3 times.
On paper that makes sense however in reality it doesn’t work like that, batteries get less efficient overtime.
The tables below show how many charges a Powerbank size will give you at 70% capacity:
The 3000mAh is the most compact option, a Powerbank designed as a backup boost and great for promotional giveaways.

The 5000mAh is practical and still compact, designed for purpose and convenience and perfectly suitable for giveaways.

Now that you understand Powerbank sizes and capacity, there are a few things to keep in mind.
Firstly, efficiency matters. Powerbanks naturally lose 30% of their capacity due to heat and voltage conversion (this is completely normal). It’s also why 10000mAh Powerbanks don’t realistically deliver 3 full charges.
Second, remember that most modern smartphones sit between 3,000 and 5,000mAh. Matching your Powerbank to your actual device makes far more sense than choosing the biggest number available.
Capacity isn’t everything.
Input speed is often overlooked. A Powerbank that recharges quickly is most of the time more convenient. Look out for ‘Quick Charge’.
Future proofing is important.
Consider future proofing. USB-C is quickly becoming the standard, so choosing a Powerbank that supports USB-C output is a smart long-term decision.
