Best Power Banks 2026: Portable Chargers for Phones, Laptops and Travel
A good power bank is the difference between a dead phone at the airport gate and a relaxed trip. The market has changed quickly: USB-C banks now charge laptops, magnetic Qi2.2 models top up phones wirelessly at up to 25W, and a pocket-sized 10,000 mAh bank can fast-charge any current phone.
This guide compares six current models using manufacturer specifications and published coverage, grouped by what you need to charge: a laptop, an iPhone without cables, a phone every day, or gear on the trail. It also explains how much of the rated capacity you really get and what US airlines allow.
What is in this guide
Quick verdict
- Best for laptops: Anker Prime Power Bank (26K, 300W)
- Best value for laptops: UGREEN Nexode 25,000mAh 145W

The best power banks in 2026
Anker Prime Power Bank (26K, 300W)
Best for laptops
- Capacity: 26,250 mAh (99.75 Wh)
- Output: Two USB-C up to 140W each, one USB-A up to 22.5W, 300W total
- Recharge: Up to 250W using both USB-C ports
- Weight: About 600 g (1.3 lb)
- Extras: Smart display, app control
- Price tier: Premium
This is the power bank for people who carry a real laptop, not just a phone. Two USB-C ports can each deliver up to 140W, which is enough to charge a 16-inch MacBook Pro or a gaming laptop at close to full speed, and the bank can still feed a phone from the USB-A port at the same time. At 99.75 Wh it sits just under the 100 Wh line most airlines use for carry-on batteries without approval.
The other headline is recharge speed. Plug two USB-C chargers in at once and Anker rates input at up to 250W, so a flat bank is usable again in well under an hour instead of an evening. The trade-offs are weight, about 600 g, and price: if you only charge a phone, everything else on this list is a better fit.
Pros
- Enough power for large laptops
- Very fast recharge with two chargers
- Just under the 100 Wh airline limit
Cons
- Heavy for a pocket or small bag
- Top price tier
UGREEN Nexode Power Bank 25,000mAh 145W
Best value for laptops
- Capacity: 25,000 mAh (90 Wh)
- Output: Up to 145W total; two USB-C and one USB-A
- Recharge: Up to about 65W over USB-C
- Weight: About 505 to 513 g
- Extras: Digital display
- Price tier: Mid-range
If you want laptop charging without paying for the Anker Prime, this UGREEN is the usual answer. Its main USB-C port is fast enough for most ultrabooks and 14-inch laptops, a second USB-C port handles a tablet or phone, and the display shows the remaining charge so you are not guessing. At 90 Wh it is also comfortably inside airline carry-on limits.
The compromises are in the details. UGREEN’s own pages describe the per-port split slightly differently, but the bank shares its 145W across ports, so two laptops at once will each charge slower. Recharging tops out around 65W, which means a few hours on a typical charger rather than the Anker’s hour.
Pros
- Laptop-level output for a mid-range price
- Display shows remaining charge
- Under the 100 Wh airline limit
Cons
- Slower to recharge than the Anker Prime
- Output is shared when several devices charge

UGREEN MagFlow Qi2 25W Magnetic Power Bank (10,000mAh)
Best magnetic for iPhone
- Capacity: 10,000 mAh
- Wireless: Qi2.2 magnetic, up to 25W on supported phones
- Wired: Built-in USB-C cable plus a USB-C port (cable version)
- Size: About 110 x 70 x 21 mm
- Compatibility: MagSafe iPhones and Qi2 Android phones
- Price tier: Mid-range
A magnetic power bank snaps onto the back of the phone, so you can keep using it while it charges, with no cable hanging off. UGREEN’s MagFlow was among the first power banks certified for Qi2.2, the version of the standard that raises magnetic wireless charging to 25W on phones that support it. Older MagSafe and Qi2 phones still work, just at their own lower wireless speed.
The version with a built-in USB-C cable is the most practical: the cable recharges the bank and can also charge a second device, so you do not need to pack a separate lead. Like all magnetic banks it is thicker than a plain 10,000 mAh brick, and wireless charging always wastes some energy as heat, so you get fewer full phone charges than the capacity suggests.
Pros
- Snaps on and charges while you use the phone
- Qi2.2, up to 25W on supported phones
- Built-in cable on the cable version
Cons
- Thicker than a plain 10K bank
- Wireless charging is less efficient than a cable

Anker Nano Power Bank (10K, 30W, Built-In USB-C Cable)
Best everyday carry
- Capacity: 10,000 mAh
- Output: Up to 30W from the built-in USB-C cable
- Ports: Built-in USB-C cable plus an extra port
- Recharge: Through the same built-in cable
- Weight: About 215 g (7.6 oz)
- Price tier: Budget to mid-range
The built-in cable is the reason to buy this one. It doubles as a strap, it charges your phone, and it recharges the bank itself, so the most common power bank failure, forgetting the cable, simply cannot happen. 30W is enough to fast-charge any current iPhone or Android phone and even to top up a tablet or a small laptop slowly.
At about 215 g and roughly the size of a deck of cards, it disappears in a jacket pocket or a small bag. 10,000 mAh typically means around two full charges of a modern phone. If the built-in cable ever wears out, the whole bank goes with it, which is the trade-off for the convenience.
Pros
- Cable is always with you
- Fast-charges any current phone
- Small and light
Cons
- A damaged built-in cable means replacing the bank
- Not enough output for most laptops

CUKTECH 10 Mini Power Bank
Best compact budget pick
- Capacity: 10,000 mAh (36 Wh)
- Output: Up to 55W from one USB-C port, USB-A up to 33W
- Multi-device: About 20W total when several ports are used
- Size: About 90 x 50 mm
- Weight: About 211 to 217 g
- Price tier: Budget
CUKTECH, a charging brand from Xiaomi’s ecosystem, packs an unusual amount of power into a very small bank. A single USB-C port can deliver up to 55W, which charges phones at full speed and can keep a light laptop going, from a bank that is shorter than most phones are wide. Expert Reviews named it a budget pick for exactly that mix of size and output.
Read the fine print on multi-device charging: with more than one port in use, total output drops to around 20W, so it is best treated as a one-device-at-a-time bank. Independent testing also found its usable capacity about average for the class rather than outstanding.
Pros
- Very small for 10,000 mAh
- Up to 55W from one port
- Budget price tier
Cons
- Output drops sharply with two devices
- Average usable capacity
Nitecore NB20000 Gen 3
Best for hiking and camping
- Capacity: 20,000 mAh
- Output: Two USB-C, up to 22.5W each; about 15W when both are used
- Water resistance: IPX5
- Weight: About 291 g (10.3 oz)
- Size: 118 x 69 x 21.5 mm
- Price tier: Mid-range
Backpackers count grams, and this is one of the lightest 20,000 mAh banks you can buy at about 291 g. Nitecore uses a carbon fiber shell and rates it IPX5, so rain and splashes on the trail are not a problem. Twenty thousand mAh is enough for several phone charges plus a headlamp or GPS over a long weekend away from outlets.
It is built for capacity per gram, not speed. Each USB-C port tops out at 22.5W, and using both at once drops total output to about 15W. There are no USB-A ports; Nitecore includes a USB-C to USB-A adapter for older gear. For laptops, look at the Anker Prime or UGREEN Nexode instead, and for multi-day trips pair it with one of our solar chargers.
Pros
- Very light for 20,000 mAh
- IPX5 water resistance
- Plenty of capacity for a weekend
Cons
- Slow when charging two devices
- No USB-A ports, adapter only
How to choose a power bank
Capacity: what mAh really gets you
The mAh number on the box is measured at the battery cell’s internal voltage. Converting it to the higher voltage your phone or laptop uses, plus heat losses, means you typically get about 60 to 70 percent of the rated capacity into your devices. In practice a 10,000 mAh bank gives a modern phone around two full charges, and a 20,000 mAh bank around four.
Output: phones, tablets and laptops
Phones charge at full speed from 20 to 45W, so almost any current USB-C bank is enough. Tablets like 30W or more. Laptops are where output matters: thin 13 and 14-inch models want 45 to 65W, and larger performance laptops 100W or more. Check the per-port figure, not just the total, because many banks split their output when more than one device is connected. You will also need a cable rated for the wattage; see our USB-C cables guide.
Flying with a power bank
In the US, the FAA and TSA require power banks to travel in carry-on bags, never in checked luggage. Batteries up to 100 Wh need no approval; 100 to 160 Wh need airline approval, and larger ones are not allowed. Every bank in this guide is under 100 Wh. Several airlines now also restrict using or charging power banks during the flight, so check your carrier’s rules before you go. For the rest of the travel kit, see our USB-C travel adapters and compact travel power strips.
Magnetic wireless or cable?
Magnetic banks are convenient: they stick to the phone and let you keep using it. Cables are faster and more efficient, so a wired bank delivers more charges from the same capacity. Qi2.2 narrows the speed gap, with up to 25W on supported phones. If you already use a 3-in-1 wireless charging stand at home, a magnetic bank fits the same habit on the go.
Safety and certification
Buy from established brands that publish full specifications and certifications, and be wary of unbranded banks claiming implausible capacities. Stop using any bank that swells, gets very hot or smells odd, and check the manufacturer’s site for recalls: several big brands have recalled specific models in recent years. Store banks partly charged, around half, if they will sit unused for months.
Power banks also make good small gifts; you will find more ideas in our tech stocking stuffers and Christmas tech gifts guides. For keeping a phone alive in a car breakdown, see winter car emergency kits.
Power bank FAQ
What size power bank do I need?
For a phone, 10,000 mAh is the best balance: about two full charges in a pocket-sized bank. For a phone plus tablet or several days away, choose 20,000 mAh. For a laptop, pick 20,000 mAh or more with at least 65W USB-C output.
Can I take a power bank on a plane?
Yes, in your carry-on bag only. Power banks up to 100 Wh are allowed without approval on US flights; 100 to 160 Wh need airline approval. All picks in this guide are under 100 Wh. Some airlines also limit using power banks during the flight.
Can a power bank charge a laptop?
Only if it has a USB-C port with enough output and your laptop charges over USB-C. Thin laptops need about 45 to 65W, larger ones 100W or more. The Anker Prime (up to 140W per port) and UGREEN Nexode 145W are the laptop picks here.
How long does a power bank last?
Most lithium-ion banks keep useful capacity for roughly 300 to 500 full cycles, which is a few years for most people. Heat shortens battery life, so avoid leaving a bank in a hot car or in direct sun.
Are magnetic power banks worth it?
If you want to keep using your phone while it charges without a cable, yes. They are less efficient than a cable, so you get fewer full charges from the same capacity. Qi2.2 models such as the UGREEN MagFlow charge supported phones at up to 25W.
Which power bank should you buy?
Final verdict
For most people charging a phone, the Anker Nano 10K with its built-in cable is the easiest everyday pick, and the CUKTECH 10 Mini is the budget alternative. iPhone owners who want to charge without a cable should get the UGREEN MagFlow Qi2 25W. For laptops, the Anker Prime 26K is the most powerful and fastest to recharge, while the UGREEN Nexode 25,000mAh covers most laptops for less. Hikers should take the light, water-resistant Nitecore NB20000 Gen 3.
- Best for laptops: Anker Prime Power Bank (26K, 300W)
- Best everyday carry: Anker Nano Power Bank (10K, 30W, Built-In USB-C Cable)
