How to Choose the Right Power Bank
A power bank is only useful if it matches how you actually use your devices. Buy too small and it dies before your phone is full; buy the wrong ports and it charges slowly. Here's how to pick the right one.
1. Capacity (mAh) — how much charge it holds
- 5,000 mAh — one full phone charge; ultra-portable.
- 10,000 mAh — the sweet spot: ~2 phone charges, still pocketable.
- 20,000 mAh+ — multiple charges or a tablet/laptop top-up for travel.
2. Output wattage — how fast it charges
Look for USB-C Power Delivery (PD). 18–22.5W is fine for phones, while 45–65W lets you fast-charge tablets and even some laptops.
3. Ports
Make sure it has the right mix of USB-C and USB-A ports for your devices, and that it can charge more than one device at a time if you need it to.
4. Pass-through & safety
- Pass-through charging lets you charge the power bank and your phone at the same time.
- Choose one with multiple protections (over-charge, over-heat, short-circuit).
- Check for safety certifications for peace of mind.
