The 5 Best Portable Chargers
A power bank should solve the one device that dies first on your trip. For a phone, I would choose a manageable 10,000mAh pack and the cable I actually use; a large laptop bank is unnecessary weight unless its USB-C output meets the computer's wattage requirement. Capacity printed in milliamp-hours does not equal energy delivered to the phone after conversion losses. If you fly, check the bank's watt-hour label and the airline's current battery rules before packing it in your carry-on.
The INIU is my starting point for a long phone day. Its smaller 45W sibling trades energy reserve for less bulk, while the Anker with an attached cable solves a different travel annoyance. MagGo only makes sense for a compatible iPhone; the large Anker earns its place when a laptop must run between outlets. Pick the device first, then the bank.

01 — INIU
Best phone-first capacityINIU Power Bank
I would begin with this INIU bank if a phone needs a dependable reserve through a long day and the bag still has room for a separate pack. Its USB-C connection makes more sense than chasing an exaggerated number of full recharges.
It leads for ordinary phone use, not laptop use. The smaller 10,000mAh INIU below is easier to carry, and the 25,000mAh Anker is the one to inspect for a computer. Compare watt-hours and exact output before assuming capacity tells the whole story.

You only want a tiny emergency top-up.
What I like
+Useful phone-focused energy reserve.
What to weigh
−More bag weight than a compact pack.
02 — INIU
Best compact higher-output pickINIU 10,000mAh 45W
This 10,000mAh INIU is the cleaner answer when you want a smaller pack but still care about a listed 45W USB-C output. I would consider it for a phone or a light USB-C device whose charging requirements fall within that limit.
It sits second because 45W is not a promise to run every laptop, and a detached cable can still be forgotten. Check your device’s connector and power needs; the Anker with a built-in cable makes packing simpler.

Your laptop requires substantially more power.
What I like
+Compact pack with listed 45W output.
What to weigh
−Limited energy capacity and cable checks.
03 — Anker
Best built-in cable convenienceAnker 10,000mAh 30W
Anker’s 10,000mAh bank removes one small but common travel failure: leaving the USB-C cable behind. I would choose it for a daily commute or airport day when a phone and a compact charger need to fit in the same pocket.
It is third because the integrated cable and 30W output trade away the INIU 45W headroom. Confirm the phone uses USB-C; an older Lightning device needs another lead. A built-in cable also deserves a look at replacement options if it wears.

View on Amazon ↗Phone owners who forget separate cables.
You need Lightning or higher-output charging.
What I like
+One fewer cable to pack.
What to weigh
−Built-in cable limits connector choice.
04 — Anker
Best magnetic iPhone top-upAnker MagGo Power Bank
MagGo is for a compatible iPhone owner who wants a pack attached to the handset while moving around, rather than a cable trailing into a bag. I would choose that handling benefit over raw capacity only when the phone and case support the magnetic setup.
It ranks fourth because magnetic convenience costs more and wireless transfer wastes some energy. If your priority is the most delivered charge per dollar, either 10,000mAh wired pack is the stronger choice.
Specifications: Exact Amazon product listing ↗
View on Amazon ↗Compatible iPhones used while walking or commuting.
You need maximum value or a non-magnetic phone.
What I like
+Cable-free attached top-ups.
What to weigh
−Higher cost and wireless losses.
05 — Anker
Best laptop-capable reserveAnker 25,000mAh Laptop Bank
This larger Anker exists for a different problem: keeping a USB-C laptop working away from a socket. Its 25,000mAh class and higher power path justify the size when the laptop’s input can use them.
It finishes fifth for a general portable-charger list because a phone-only traveler pays in cost and weight for capacity they may not need. Check the exact watt-hour mark against airline rules and the laptop’s input before buying it as a travel solution.
Specifications: Exact Amazon product listing ↗
View on Amazon ↗Laptop work between outlets.
You only need to refill a phone.
What I like
+Higher-capacity laptop-oriented design.
What to weigh
−Large and expensive for phone-only use.

FAQ — Portable Chargers
01Can I put a power bank in checked baggage?+
The FAA says spare lithium-ion batteries and power banks belong in carry-on baggage. Check the watt-hour rating and your airline’s current rules before travel.
02Will any USB-C power bank charge a laptop?+
No. Compare the laptop’s required USB-C power input with the bank’s output rating and cable. Phone-oriented banks may charge too slowly or not at all.
The short answer
Start with the INIU Power Bank.
I recommend it for long phone days away from an outlet. Choose something else if you only want a tiny emergency top-up.
