What Makes a Power Bank “Portable”?
While all power banks are technically rechargeable batteries, not all are truly “portable”. A portable power bank is defined by three factors:Size: It should easily fit in your pocket, purse, or daily carry bag.

So, what defines a good portable power bank among so much chooses?
1. Capacity (mAh): Know What You’re Buying Power For
mAh (milliamp hours) is the unit that defines how much energy a power bank stores. For example:
5000mAh = roughly 1 smartphone charge
10000mAh = 2–3 charges for most phones
20000mAh = up to 5 charges or 2 devices simultaneously
2. Charging Speed: Why Wattage Matters
A fast portable power bank should support output speeds that match or exceed your device’s charging capability.
For phones, 25W is considered enough.
For laptops, 45–65W is ideal.The INIU P50-E1 offers 45W PD (Power Delivery) fast charging, capable of charging a MacBook Air to 42% charge in just 25 minutes.
