The Anker Prime 27650mAh is the most capable consumer power bank available. 250W total output means it can fast-charge a MacBook Pro and two phones simultaneously. The smart display shows wattage, remaining battery, and estimated time to full.
The Anker 737 is the go-to power bank for laptop-dependent travelers. 140W two-way USB-C PD charges a MacBook Air from dead to full in under 2 hours, and the smart display shows exactly how much power remains.
The Baseus Blade is the most remarkable form factor engineering in the power bank category. At 14.5mm thin, it fits in a MacBook sleeve yet delivers 100W USB-C PD — enough to fast-charge any USB-C laptop.
Ugreen has earned serious credibility in the charging accessories space, and the 20000mAh power bank delivers 130W output across three ports at a price that undercuts Anker. The LED display is brighter and easier to read than most competitors.
The Anker 622 MagGo is the best-selling MagSafe power bank for a reason. At $29-45, it attaches magnetically to your iPhone, charges wirelessly while you use it, and the kickstand lets you prop up the phone — perfect for watching video on the go.
The Nitecore NB10000 Gen2 is the top choice for ultralight backpackers and thru-hikers. At 155 grams, it's 40% lighter than most 10,000mAh competitors while still delivering 22W fast charging.

A power bank is now often expected to charge a laptop as well as a phone, so output wattage matters as much as capacity. Anker lists 300W total output for the Prime Power Bank (26K, 300W), with up to 140W from each USB-C port, and 140W for the Anker 737. Baseus rates the Blade for USB-C devices that draw 100W or less, and UGREEN lists 130W combined on the Nexode 20000mAh 130W. For phones only, a smaller pack such as the 5,000mAh Anker 622 MagGo or the 150 g Nitecore NB10000 Gen2 is easier to carry.
Watt-hours, not milliamp-hours, decide whether a power bank can fly. The FAA allows spare lithium-ion batteries up to 100Wh in carry-on bags, requires airline approval from 101 to 160Wh, and forbids anything larger. TSA says power banks must go in carry-on bags, never checked luggage. Anker lists the Prime 26K at 99.75Wh. Reviews and Anker's FAQ give 86.4Wh for the 737, and Nitecore lists 38.5Wh for the NB10000 Gen2. Standard 20,000mAh packs such as the Baseus Blade and UGREEN Nexode also sit well under 100Wh. Airlines can set stricter rules, so check your carrier before you fly.
The most common mistake is buying on the biggest number on the box. A high total output is usually shared across ports, so check what a single USB-C port can deliver to your laptop. Weight is the other trade-off: Anker lists the 737 at 630 g and the Prime 26K at 600 g, while Nitecore lists the NB10000 Gen2 at 150 g. Finally, compare current prices rather than launch prices, because street prices in this category move often.
Check the maximum wattage of a single USB-C port, not just the combined total. Anker lists up to 140W per USB-C port on the Prime 26K and 140W on the 737, while UGREEN's 130W figure for its Nexode 20000mAh model is a combined total across ports. If your laptop's charger is rated higher than the port, it will charge slowly or only hold its level.
The FAA allows spare lithium-ion batteries up to 100Wh in carry-on bags without airline approval. Every pack in this ranking is rated under 100Wh, with the Anker Prime 26K closest at 99.75Wh. Packs above 100Wh need airline approval, and above 160Wh they are not allowed.
A 5,000mAh magnetic pack like the Anker 622 gives a phone a partial top-up, while 20,000mAh and larger packs are sized for laptops or several devices. Buy for your longest day away from an outlet, not for the largest number available, because capacity adds weight.
Laptop-class packs are heavy: Anker lists 630 g for the 737 and 600 g for the Prime 26K, and UGREEN's 130W model is listed at 480 g. Nitecore lists the NB10000 Gen2 at 150 g with a 10.6 mm thick body, which suits hikers and anyone who only needs to charge a phone.
Count the devices you charge at once and the connectors they use. The Baseus Blade has two USB-C and two USB-A ports, the Anker 737, Prime 26K, and UGREEN 130W each have two USB-C and one USB-A, and the Nitecore NB10000 Gen2 has one of each. Nitecore's newer Gen 3 drops USB-A, so older cables need an adapter.
Magnetic packs like the Anker 622 MagGo are convenient because nothing dangles from the phone, but Anker rates its wireless output at 7.5W. Its USB-C port supplies up to 12W. If charging speed matters more than convenience, use a cable.
Yes, in your carry-on bag. TSA does not allow power banks in checked luggage. The FAA allows spare lithium-ion batteries up to 100Wh without airline approval, allows 101 to 160Wh with airline approval, and forbids anything over 160Wh. Airlines may set stricter limits, so check with your carrier.
Anker rates it at 99.75Wh and lists it as flight-approved. That is under the FAA's 100Wh limit for spare batteries, so no airline approval is needed under FAA rules. It must still travel in your carry-on bag.
Air travel limits are written in watt-hours, which account for battery voltage as well as capacity. Two packs with similar mAh can have different Wh ratings, so look for the Wh figure printed on the pack or listed by the maker. For example, Anker lists 26,250mAh and 99.75Wh for the Prime 26K.
It can if it supports USB-C Power Delivery at a wattage close to your laptop charger's rating. Anker's 737 and Prime 26K list up to 140W per USB-C port, and Baseus rates the Blade for devices drawing 100W or less. Lower-wattage packs will charge a laptop slowly or only slow its drain.
Anker rates its wireless output at 7.5W for iPhone 12 and later, which is slower than charging with a cable. The pack also has a USB-C port rated at up to 12W. It holds 5,000mAh, so expect a partial top-up rather than several full charges.
The Nitecore NB10000 Gen2, which Nitecore lists at 150 g for 10,000mAh. It also carries an IPX5 water-resistance rating and a carbon-fiber body. It is built for phones and small devices, with up to 20W from its USB-C port.
Buy from the brand's own store or its authorized storefront on a major retailer, and check that the listed capacity, Wh rating, and model number match the maker's product page. A listing that claims far more capacity than the brand's own specs is a warning sign.
