The 9 Best Fastest Portable Chargers for iPhone in 2027

For an iPhone 16 or 17, this is the pack we'd buy first. It charges at the full 25W those phones accept wirelessly, and Notebookcheck saw an iPhone 16 and an iPhone 17 Pro go from 10% to 80% in 40 minutes, against 90 minutes for Baseus's older Qi2 model. It stayed cool doing it, peaking around 36C.

Two hours into a road trip, the phone is running maps at 40% and you pull in for gas. Snap the pack on, and by the time you're back on the highway the battery is out of the danger zone. The 45W built-in USB-C cable doubles as a strap and can top up a friend's phone or keep a MacBook Air going. By default the cable takes priority; press the button once to run both.

But the downsides are real, if small. Four LEDs give a rough gauge, not a percentage, and the magnet grips less firmly through a case. With every output busy, total power drops to 15W shared. On an iPhone 16 or newer, it's the one we'd buy. Want an exact readout? The UGREEN MagFlow (#4) has one.

Here's the quickest way to put real charge into a USB-C iPhone away from the wall: a cable. This Anker sends up to 40W into an iPhone 17, and Pack Hacker saw an iPhone 16 Pro and 15 Pro reach 50% in 25 to 27 minutes. That beats every magnetic pack on this list, and only the much heavier Anker Prime (#6) is faster by cable.

Picture a half-hour coffee stop before boarding. You pull out the 2.3 ft retractable cable, set the phone beside your cup, and walk to the gate with about half a battery more than you sat down with. The screen shows watts going out, temperature and battery health. An iPhone 14 or older needs a USB-C to Lightning cable, which isn't included.

So what's the catch? Owners on r/anker confirm it refills at 30W at most and slows its output once it warms up, and Trusted Reviews saw it fall to 30W before half its charge was gone. It's chunky for a 10K pack, too. Rather have something that rides on the phone? The Baseus PicoGo AM52 (#1) does that.

If bulk is what's kept you away from magnetic packs, start here. The SnapGo Air is about half an inch thick and around 195g, yet it charges at 25W on an iPhone 16 or newer and adds 45W wired over USB-C. Trusted Reviews saw an iPhone 17 Pro Max climb from 51% to 80% in 25 minutes.

Theme park days are where it earns its place: photos and video on a Pro Max from opening time to the fireworks. This rides on the back without making the phone awkward in one hand, and the short GoCord cable is there when a friend's phone needs help. It fits an iPhone Air neatly and sits slightly past the bottom edge of an iPhone 17 Pro.

But heat is the trade-off. Hamer Reviews found the 45W wired output lasted only 5 to 15 minutes before settling near 30W, and long wireless sessions slow down as well. The cable is tied on with thin string, and the screen shows battery level only. Our call: for an all-day magnetic pack, yes. On an iPhone 12 to 15, the Anker MagGo Slim (#9) suits your phone just as well.

This is the magnetic pack for anyone who likes knowing the numbers. The screen shows an exact battery percentage, and the speed backs it up: Macworld timed an iPhone 16 Pro from 0 to 50% in about 32 minutes at 25W, against 44 minutes for a 15W iPhone 15 Pro.

It pays off as you grab your bag before a 12-hour shift. One glance tells you the pack has enough left, so the wall charger can stay home. The built-in 30W USB-C cable handles camera batteries or a Nintendo Switch 2 as well, and three devices can charge at once, though they share the power.

But it's chunky. At 254g and 21mm thick it drags on the phone, and several owners on UGREEN's store mention it running hot and feeling bulky. Capacity is middling, at about 1.44 iPhone 16 Pro charges in Macworld's measurements. Is it worth the bulk? For bag carry, yes. To keep a pack on the phone all day, the INIU SnapGo Air (#3) is far thinner.

So you want fast charging and don't want to pay for magnets? This is the pack. INIU's P50 charges an iPhone at full wired speed from a body small enough for a jeans coin pocket, and TechRadar measured 32.1Wh usable of its 36Wh rating, better than most 10K packs.

Now take twenty minutes between afternoon classes. The pack sits in your pocket, the iPhone charges on the short lanyard cable, and you walk into the lecture with plenty left for the evening. Pack Hacker got an iPhone 17 about 1.5 to 2 times per fill, and hikers and one-bag travelers on Reddit keep recommending it as a light, affordable 10K pack.

Still, the limits are clear. Heat cuts its 45W to 30W or less within minutes on big loads like a laptop, though phone charging isn't hurt by it. Use two or three ports and they share 15W. The lanyard can also pop loose in a bag. On a budget, it's the pack we'd pick. Want a long cable and a watt display? The Anker Nano (#2) is the step up.

Nothing here charges an iPhone faster by cable. The Prime sends 40W into an iPhone 17, and Jackington took an iPhone 17 Pro Max from 1% to 50% in 22 minutes. Engadget got a near-dead iPhone 15 to 60% in half an hour. Then it does the same for a laptop, with 140W from each USB-C port at once.

A client meeting runs long, and the only outlet is behind a cabinet. Your MacBook and iPhone both plug into the bank and charge at full pace while you present. The screen shows watts per port and temperature, it stayed at or under 41C in Jackington's runs, and it refills in about an hour and a quarter from two 140W chargers. A 240W USB-C cable is in the box.

But you pay for it in weight and money. At about 600g it's a bag item, the glossy front marks easily, and the charging base is extra. If a laptop travels with your iPhone, it's worth the weight. Want a proven 140W bank for far less? The Anker 737 (#8) is it.

Most magnetic packs leave you holding the phone. This one stands it up. The built-in kickstand turns a Pro Max into a little screen on any flat surface, and keeps charging at Qi2 25W. Stefan Zanev saw an iPhone 17 Pro Max gain 19% in 15 minutes wirelessly and 29% over the 30W USB-C port.

Say you're stuck at the laundromat for an hour. Prop the phone on the folding table, start a show, and the pack keeps charging it through the dry cycle. The rear magnetic ring holds a MagSafe wallet or grip, so you don't give up your accessories, and the side display shows the percentage. A 2 ft USB-C cable comes with it.

Now the honest part. It's about twice the thickness of an iPhone in a case and overhangs anything smaller than a Pro Max. There's one USB-C port, and charging two things splits the power to 15W each. Timed results are scarce, and Belkin's previous version ran hot in a lab test, though no review of this one reports heat. For a Pro Max and lots of video, we'd still buy it. For a smaller iPhone, the INIU SnapGo Air (#3) fits better.

The 737 is the bank that keeps a whole travel kit alive. It holds a steady 140W from one USB-C port, enough for a 16-inch MacBook Pro, and its 24,000mAh battery works out to about four to five iPhone charges. TechRadar measured 73.1Wh delivered at the full 140W, a strong result.

Picture a cafe on a work trip where every outlet is taken and your laptop, iPad and iPhone are all low. They take turns on the bank at your table, and at 86.4Wh it can fly home in your carry-on, too. The display shows watts in and out, cycles and health, and the box has a 140W cable and a pouch.

What it doesn't have is a wall charger. Owners on the MacRumors forums warn that a small iPhone charger took over 4 hours to refill it, so pair it with a 100W or bigger block for the under-an-hour refill. At 630g it's heavy, too. For laptop trips, we'd still pack it. For two 140W ports at once and a bigger battery, the Anker Prime (#6) is the upgrade.

Own an iPhone 12, 13, 14 or 15? Then a 25W pack buys speed your phone can't use, because those models top out at 15W wirelessly. This slim Anker charges right at that ceiling, and MobileReviewsEh saw 44% in 30 minutes wirelessly and 53 to 55% over its 30W USB-C cable.

Say you're standing on a packed subway car, one hand on the rail, the other on your phone. The soft-touch back grips hard, taking 11 to 12 newtons to pull off against a 9.4 N average in MobileReviewsEh's results, so it isn't sliding away when the train lurches. It's 0.58 in thick, and Anker built its aluminum Qi2 module to hold 15W steady through magnetic cases.

Still, it's simpler than newer packs. There's no screen or kickstand, the port sits on the bottom, and pass-through charging was slow in one review. And at around 200g, it weighs more than its thin shape suggests. For an older iPhone, it's still the one we'd buy. On an iPhone 16 or newer, the INIU SnapGo Air (#3) charges at 25W instead.
