Best Power Banks 2025

Staying topped‑up on the move shouldn’t feel like lugging a brick or waiting an age for a light to turn green. In 2025, the best battery pack pairs serious wattage and capacity with clever extras. Here are 8 top picks that serve different charging styles without the usual compromises.

Anker Prime 20,000mAh Power Bank (200W)

You want laptop-level output in something that still fits a jacket pocket? The Anker Prime 20,000mAh Power Bank (200W) is the sweet spot. Two USB-C ports dish out 100W each—enough to top two MacBook Airs at the same time—while a third USB-A handles legacy gear.

The smart display shows exactly what’s going on—real-time battery levels, charging speeds, and input/output status—so you’re never left guessing. Even better, a 100W USB-C input refills the whole pack in about 75 minutes, so coffee-shop layovers turn into full resets rather than trickle charges. All of that lives inside a 4.9-inch shell that slips into any sling bag, making it one of the best portable battery chargers for travel.

Anker MagGo Power Bank (10K)

If you’re rocking an iPhone 12-16 and live on MagSafe, the Anker MagGo Power Bank (10K) is the daily carry to beat. Snap it on and the Qi2-certified charging pad pushes 15W wirelessly, taking an iPhone 15 from flat to 50 % in roughly 44 minutes without a cable.

A sturdy kick-stand pops out for easy viewing or StandBy mode, and the OLED read-out tells you exactly when you’ll hit 100%. Wired? The USB-C port blasts 27W—enough to hit 60% on your iPhone in half an hour. At just 0.78 inches thick, it’s slim for a 10K pack, and the magnets are strong enough that you can keep scrolling while it charges.

Anker Prime 27,650mAh Power Bank (250W)

When you need to juice a 16-inch MacBook Pro on the go, the Anker Prime 27,650mAh Power Bank (250W) is the cavalry. Each of its two USB-C ports can output 140W (PD 3.1), with a combined ceiling of 250W—so you can fast-charge a laptop and still have headroom for a tablet.

A companion Anker app lets you ping the bank if it slips behind a couch, view live stats, or schedule a “battery-health” capped charge. Despite a weekend-long 27,650mAh (99.5 Wh) reserve, this best portable charger meets most airline carry-on rules and recharges in just 37 minutes when you feed both USB-C inputs 170W.

Want a magnetic battery pack on a budget? The Anker 622 Magnetic Battery (MagGo) snaps onto any MagSafe-ready iPhone with a 9N magnetic lock that keeps it planted even when you’re walking and texting. A flip-out stand lets you prop the phone in portrait or landscape for FaceTime or StandBy mode.

Despite that extra trick, the pack stays just 0.5 in thin, so it still fits a skinny jeans pocket. Anker’s MiniCell architecture compresses the electronics, trimming weight without sacrificing the 5,000mAh capacity. Wireless output peaks at 7.5 W, while the USB-C port on the side handles wired duties or passthrough charging when you plug in.

Anker Nano Power Bank (30W, Built-In USB-C Cable) 10,000mAh

Think of the Anker Nano Power Bank (30W, Built-In USB-C Cable) as a wall-charger and cable that never has to leave your pocket. A built-in, 30W USB-C ribbon cable unfurls to fast-charge a phone, tablet, or even a lightweight laptop, and then slots back in flush. A second USB-C plus a USB-A port give you flexibility for friends’ cables.

The front color screen shows remaining capacity and time-to-full at a glance—no cryptic LEDs here. At 4.09×2.06×1.02 in, this 10K battery pack is shorter than most phones, and the looped carry handle makes airport shuffles easier. The outer shell is molded from 80% post-consumer recycled plastic, cutting the carbon footprint without skimping on toughness.

What to Consider When Choosing the Best Power Bank

Picking the right pack isn’t just about grabbing the largest number on the box. Capacity, speed, and even airline carry‑on rules all shape what will—or won’t—keep your gear alive when it matters. The checklist below walks you through every major spec, so you can zero in on the best power banks for your phone, laptop, or more.

Capacity (mAh & Wh)

Ask yourself first: how much power do you need? A 10,000 mAh pack tops most phones twice; 20,000 mAh handles a tablet or Nintendo Switch overnight; anything above 20,000 mAh is mainly for laptops but might add airport scrutiny.

Milliamp-hours (mAh) tell you how big the fuel tank is, but airlines care about watt-hours (Wh). CATSA follows IATA guidelines: spare lithium batteries, including power banks, must ride in carry-on, not checked bags, and must be under 100Wh (about 27,000mAh) unless you get airline approval (up to two spares 101–160Wh).

Convert with Wh = (mAh × V) ÷ 1000. A 20,000 mAh pack at 3.7V equals roughly 74Wh, well under the 100Wh ceiling.

Output Power & Fast-Charging Standards

For faster charging, make sure your charger supports USB-C Power Delivery (PD). If you’re just giving your phone a quick boost, 20–30W should do the trick. But if you’re powering up a tablet, laptop, or multiple devices, you’ll want more juice—PD 3.0 delivers up to 100W, while PD 3.1 goes all the way up to 240W, which is even enough for power-hungry gaming laptops.

Some devices, like Samsung Galaxy phones, benefit from PPS (Programmable Power Supply), which adjusts the voltage on the fly for cooler, quicker charging. And if your phone supports Quick Charge 5, you can see speeds over 100W. To get the fastest results, always match your device with the right charging protocol.

Re-Charge (Input) Speed

Look for a good power bank that accepts 45–100W USB-C input if you don’t want to wait hours for a refill; some hit 0–100 % in under 90 minutes with a GaN wall brick.

Ports, Cables & Connector Future-Proofing

USB-C is the default now. By 2022, USB-C already appeared on 96% of new laptops and nearly 60% of phones. Keep one USB-A if you still carry older cables but prioritize multiple USB-C ports or an integrated cable for future-proof convenience.

Size, Weight & Form Factor

Higher watt-hours mean heavier cells. For pockets, stay under 250g (9oz); for backpacks, weight matters less than durability (metal shells, rubber end-caps). Slim packs often sacrifice peak wattage, so balance bulk against output needs.

Safety Certifications & Thermal Management

A UL-listed mark shows the bank passed tests for over-current, capacity accuracy, and cell robustness—the quickest way to filter out sketchy clones. Moreover, look for on-board temperature sensors and battery-management systems that shut down at unsafe conditions rather than cooking your phone.

Wireless Charging

If you’re an iPhone user who hates juggling cables, a magnetic wireless battery pack can feel liberating—just snap your phone on the pad and walk away. The latest Qi2 standard (essentially the cross-platform follow-up to Apple’s MagSafe) uses a ring of magnets to line up the coils, cutting energy loss and boosting speeds to 15W, double the old 7.5W Qi ceiling.

Pass-Through & Other Smart Features

Pass-through lets the bank charge itself and your devices sequentially from one outlet—handy in hotel rooms—but it does lengthen total charge time. Extras like LED/OLED screens for exact percentages, Bluetooth apps for locating the power bank, or built-in kickstands for snap-on packs can be useful. Decide if they justify the added cost.

Conclusion

At the end of the day, the best power bank is the one that fits your routine without adding bulk or hassle. Whether you need something ultra-compact for everyday use, a sleek Qi2 battery pack that snaps on or a 20,000-mAh beast for road trips and long flights, the right pick makes all the difference. The models we’ve highlighted are fast, reliable, and built for how you actually use your tech. Just figure out what matters most—speed, size, ports—and you’ll be good to go.

FAQs

Which brand is the best power bank?

No single brand fits every need, but if you want a reliable, “can’t‑go‑wrong” option, look at Anker. The company backstops its battery packs with strong safety certifications, offers everything from sleek snap-on Qi2 wireless battery packs to 250W laptop bricks, and supports them with an 18‑month (sometimes longer) warranty. That mix of performance, protection, and after‑sales help makes Anker the brand most people can buy with confidence.

What are the best power banks on the market?

“The best” depends on what you’re charging and how you carry it. For all‑round daily use, a Qi2-certified Anker MagGo wireless pack 10K keeps your iPhone topped up without cables. Need serious juice? The Anker Prime 20,000 mAh (200W) covers two laptops at once. If you just want a tiny emergency boost, the Anker Nano 22.5W slips into any pocket. Match the capacity and wattage to your heaviest device and you’ll have the best power bank for your routine.

Should I get 10,000mAh or 20,000mAh power bank?

Ask yourself how long you’re away from an outlet. A 10,000 mAh pack is slim, light, and usually costs less; it refills most phones twice and is perfect for commuting or day trips. A 20,000 mAh pack doubles that stamina and often adds higher‑watt USB‑C ports for tablets or ultrabooks, but it’s heavier and takes longer to recharge. If you travel overnight, juggle multiple devices, or run power‑hungry gadgets, go 20,000 mAh. For pocket carry and quick top‑ups, 10,000 mAh keeps the weight—and the price—in check.
