The best power banks for phones, tablets, and laptops
The Anker Laptop Power Bank is the best all-around pick, with generous capacity, fast charging, and cables built in.
| Best overall | Best value | Cheapest that's still good | |
|---|---|---|---|
| Product | Anker Laptop Power Bank (A1695) | UGREEN Nexode Power Bank 12000mAh 100W | Amazon Basics Slim Portable Charger (10,000 mAh) |
| Price | about $120 | about $49 | about $20 |
| Why | WIRED names it its best power bank after testing more than 100, and reports fast charging across phones, tablets, and laptops. Its 25,000mAh capacity, built-in cables, and 165W total output make it versatile for most people who also carry larger devices. | Tom’s Guide calls it its best budget portable charger, citing 100W output and a compact, bag-friendly size for about $49. That is substantially cheaper than the Anker while still offering enough power for compatible phones, tablets, and some laptops. | Tom’s Guide tested it against four other Amazon power banks under $20 and found it reliable, with a $19.98 price in the review. In its iPhone 17 test, it sustained a fully charged phone for 5 hours 17 minutes and took 13 minutes to bring a drained phone to 25%. |
| Good to know | It costs much more and weighs more than a basic phone-only power bank. | Charging two devices at once limits output to just 10W. | It has no built-in cable or screen, so bring a cable and rely on basic indicator lights. |

What matters
Match capacity and output to what you carry: phones need less power than laptops, and higher wattage can charge compatible devices faster. Built-in cables are handy, but size and weight matter if you want a pocketable backup.
Who this is for
These picks suit people who want reliable backup power, from an everyday phone top-up to charging a laptop on the go. The large CUKTECH is for trips and multiple devices, not light pockets.
The picks, one by one
Best overall: Anker Laptop Power Bank (A1695)
WIRED names it its best power bank after testing more than 100, and reports fast charging across phones, tablets, and laptops. Its 25,000mAh capacity, built-in cables, and 165W total output make it versatile for most people who also carry larger devices. It has a retractable USB-C cable and a second built-in USB-C cable that doubles as a carry loop, so you needn’t pack a separate cable. A screen shows remaining charge, power flow, temperature, and battery health. WIRED says it recharges in about two hours and reports a year of use without performance problems. Skip it if you only need a small, inexpensive phone backup; it is larger and pricier than that calls for.
Good to know: It costs much more and weighs more than a basic phone-only power bank.
See on AmazonBest value: UGREEN Nexode Power Bank 12000mAh 100W
Tom’s Guide calls it its best budget portable charger, citing 100W output and a compact, bag-friendly size for about $49. That is substantially cheaper than the Anker while still offering enough power for compatible phones, tablets, and some laptops. It has USB-C and USB-A ports, plus a display that shows the remaining charge. Tom’s Guide says it can recharge at up to 65W, which helps refill the bank quickly. The listed weight is 10.9 ounces, so it is small but not especially light. Skip it if you regularly charge two devices at once: using both ports limits output to 10W.

Tom’s Guide tested it against four other Amazon power banks under $20 and found it reliable, with a $19.98 price in the review. In its iPhone 17 test, it sustained a fully charged phone for 5 hours 17 minutes and took 13 minutes to bring a drained phone to 25%. It is a straightforward 10,000mAh charger with USB-C and USB-A ports. Tom’s Guide also measured a 1-hour-18-minute recharge using a 65W adapter. The simple design keeps the price down, but means you get neither a screen nor built-in cables. It is the budget choice for phone charging, not a laptop-power option.
Good to know: It has no built-in cable or screen, so bring a cable and rely on basic indicator lights.
See on AmazonHow we chose
Reviewers charged phones, tablets, and laptops, checked charging speed and power remaining, and assessed size and everyday convenience. Tom’s Guide also ran an iPhone 17 under a demanding graphics workload until each tested bank ran out, then timed recharging and phone charging. Danilli read the reviews and tests listed below and compared current prices; it does not take money from brands to pick a product.
