Our Top Picks
Before comparing models, a note on what “100 Wh” means. Watt-hours measure total stored energy: volts multiplied by amp-hours. Most 100 Wh banks are listed as roughly 27,000 mAh at 3.7 V, but usable energy after conversion losses is lower, often around 60 to 70 percent of the rated figure. Manufacturers’ output ratings (such as 100W or 130W) describe peak charging speed, not total capacity. Keep both numbers separate when comparing.

Buying Guide
Check the Watt-Hour Rating and Real Usable Energy
A 100 Wh rating is the ceiling for most airline carry-on rules, but usable energy is always less because of voltage conversion and heat. For a laptop with a 60 Wh battery, a 100 Wh bank will give roughly one full charge, sometimes slightly less. Plan around that margin.
Good picks for this: Baseus Laptop Portable Charger 100W 20000mAh, Anker Laptop Power Bank 25,000mAh
Match Output Wattage to Your Laptop
Check your laptop charger’s rated wattage. A bank with lower output than your laptop needs will charge slowly or not at all under load. Look for USB-C PD support and a combined output figure, since sharing ports lowers per-device speed.
Good picks for this: UGREEN Nexode 20000mAh 130W Portable PD Power Bank, Portable Charger for MacBook Laptop
Count and Type of Ports
USB-C ports are the most useful for modern laptops and phones. Multiple ports let you charge several devices at once, but the total output is shared. Check whether the bank includes a cable and whether that cable supports the wattage you need.
Good picks for this: Anker Laptop Power Bank 25,000mAh, Orfeika 20000mAh Power Bank
Size and Weight for Carrying
Banks in this capacity class typically weigh between about 450 and 700 grams depending on build and cell type. Measure the space in your bag before buying. A slimmer body helps in a crowded carry-on, while a larger body may dissipate heat better under load.
Good picks for this: INIU Laptop Power Bank 25000mAh, Anker Power Bank 20,000mAh
Airline and Travel Compliance
Most airlines follow the FAA and international rules that allow lithium batteries up to 100 Wh in carry-on bags without approval, and limit spares. Check the rating printed on the bank and your airline’s current policy before you fly. Keep the bank in your carry-on, not checked luggage.
Good picks for this: INIU Laptop Power Bank 25000mAh, Portable Charger for MacBook Laptop, 20000mAh
Display and Monitoring
An LED or TFT display shows remaining charge, input and output. This is helpful for planning, but it uses a small amount of power. If you do not need live readouts, a simpler indicator is fine.
Good picks for this: UGREEN Nexode 20000mAh 130W Portable PD Power Bank, Orfeika 20000mAh Power Bank
Build Quality and Safety Features
Look for overcharge, over-temperature and short-circuit protection in the specifications. Buy from the brand’s own listing and avoid units with no rating label. Store the bank at room temperature and avoid leaving it in hot cars. If a bank becomes swollen, hot or smells unusual, stop using it and follow the manufacturer’s disposal guidance. For safety questions specific to your situation, consult the manufacturer or a qualified professional.

FAQ
Is a 100 Wh power bank allowed on planes?
In most cases yes, in carry-on baggage without airline approval. Rules vary by country and carrier, so check your airline before you fly and confirm the Wh rating printed on the bank.
How many times can a 100 Wh bank charge a laptop?
It depends on the laptop battery size and conversion losses. A bank rated 100 Wh typically delivers well under that in usable energy, so one full charge of a 50 to 60 Wh laptop battery is a realistic expectation, with a partial second charge possible.
What is the difference between mAh and Wh?
mAh measures charge at a given voltage, while Wh measures total energy. A 27,000 mAh bank at 3.7 V is about 100 Wh. Airlines use Wh, so check that figure rather than mAh alone.
Can a 100 Wh power bank charge a laptop at full speed?
Only if the bank’s output wattage matches or exceeds the laptop’s charging requirement, and you use a compatible USB-C cable. Lower-output banks will still charge the laptop, just more slowly.
Do multiple ports reduce charging speed?
Yes. Most banks share total output across ports, so when several devices charge at once, each receives less power. Check the combined output figure in the specifications.
How should I store a power bank?
Keep it at room temperature, away from direct sun and heat sources. Avoid full discharge for long periods and avoid leaving it charging unattended for days. If you notice swelling or heat, stop using it.
Conclusion
For most travelers the Baseus Laptop Portable Charger 100W 20000mAh offers the best balance of laptop output and port variety. Choose the Anker Laptop Power Bank 25,000mAh if you charge three or more devices at once, and the UGREEN Nexode 20000mAh 130W if your laptop needs the highest peak output. Small-bag travelers should look at the INIU, and budget buyers will find the Orfeika a practical option. Match the bank to your laptop’s wattage first, then your port needs, and always confirm current airline rules.
