Buying Guide
Travel Pro Tip: Build a “Two-Cable” Charging Kit That Actually Works
The easiest way to make an affordable power bank feel premium is to stop carrying a mess of cables. Pack just two: one short USB-C to USB-C cable for modern phones and tablets, plus one USB-C to Lightning (or USB-C to Micro-USB if you still have older gear). That covers almost everything without turning your bag into a knot.
Next, match the wall charger to your power bank. A fast power bank is only convenient if you can refill it quickly in a hotel, lounge, or coffee shop. If your power bank supports USB-C PD input, pair it with a USB-C wall charger you already trust so you are not stuck waiting half a day for a refill.
Finally, keep your power bank “half full” before transit days. Topping it off the night before is great, but in real life it gets used and tossed back in a bag. A quick weekly check keeps you from discovering an empty bank right when you need it most.

Frequently Asked Questions ▾
What size power bank is allowed on a plane?
Most travelers are safe with power banks up to 100Wh, which is the common limit for carry-on lithium batteries on many airlines. In practice, that usually means anything up to about 27,000mAh (at 3.7V) is typically fine, and the 10,000mAh to 20,000mAh range almost never raises eyebrows. Always keep power banks in your carry-on, not checked luggage, and avoid units that do not clearly label capacity.
How many charges will a 10,000mAh power bank give me?
Expect roughly 1.5 to 2 full phone charges for most modern phones, not a perfect 2 to 3. Real output is lower than the advertised capacity because voltage conversion and heat waste energy. If you are charging a phone and earbuds in the same day, a 10,000mAh bank is usually enough; if you are charging a phone plus a tablet, bump up to 20,000mAh.
Do I really need USB-C Power Delivery (PD) to travel?
It is not required, but it makes a big difference for newer phones and tablets. USB-C PD can charge compatible devices faster and, just as importantly, can recharge the power bank itself faster when you only have a short layover. If you are still using mostly USB-A cables and you charge overnight, a simple USB-A bank can still be a solid, cheaper choice.
What wattage should I look for if I want to charge a laptop?
For most USB-C laptops, look for a power bank that can output at least 45W, and ideally 60W to 65W for more dependable charging while you are using the laptop. Lower-wattage banks may connect but charge very slowly, hold the battery level steady, or stop charging under heavier loads. Also check your laptop’s charger wattage as a quick clue for what it expects.
How do I avoid buying a “cheap” power bank that is a safety risk?
Stick with recognizable brands, choose models with clear labeling (capacity, input, output), and avoid listings that make unrealistic claims about capacity or charging speed. A good affordable bank should stay only mildly warm during use, charge consistently, and not randomly disconnect. If you see swelling, a damaged casing, or overheating, stop using it immediately and replace it.
