How we rank best portable chargers under $25 for you?
We start with charging speed, because a cheap pack that trickles at 12W can't save you in the 15 minutes before you leave. Battery capacity comes next: 10,000mAh means about two phone charges, 5,000mAh about one top-up. Design and build matter because size, weight and a built-in cable decide whether the pack comes along and works without a spare cord. Phone compatibility checks USB-C, Lightning and magnets so your phone charges at full speed. Value comes last, since every pick fits the budget and the question is what each one adds.
Charging Speed30%
Cheap packs range from 12W to 45W, which is the gap between a usable phone in 20 minutes and an hour of waiting at the gate.
Battery Capacity25%
A 10,000mAh pack covers about two phone charges, a 5,000mAh one about one top-up, so capacity decides whether it lasts the trip.
Design and Build20%
Size, weight, built-in cables and magnets decide whether the pack actually comes with you and works without extra cords.
Phone Compatibility15%
USB-C, Lightning, MagSafe magnets and Galaxy fast charging decide whether your phone charges at full speed or crawls.
Value10%
Every pick fits the cap, so value is about what each extra dollar buys in speed, cables or capacity.

1. INIU Pawsible P41L-E2 (10,000mAh, 45W, Built-In Cable): Best Portable Charger under $25 Overall
If you want one cheap pack that actually charges fast, this is the one we'd buy. INIU rates it at 45W from a single port, and Too Many Adapters measured 43.2W, while everything else on this list tops out at 22.5W. In CNN Underscored's run it put over half a charge into a dead iPhone 16 and 70% into a Galaxy S25 Ultra in 30 minutes.
That speed pays off at the end of a late shift, with the rideshare 15 minutes away and your phone at 8%. The USB-C cable is built into the pack, so you plug in and get real charge back before the car pulls up. It weighs about 6.3 to 6.7 ounces, holds roughly two iPhone 16 Pro charges, adds a flashlight, and INIU backs it for three years.
The catch is sharing. Add a second device and the total drops to about 15W, and output falls to about 4W while the pack itself is on the wall. Refilling takes close to two hours. Our verdict: for one phone, it's the one to get. If friends will take turns on it, the Baseus EnerFill FC51 (#2) suits a group better.
Best for: Anyone who wants real fast charging for one phone at the lowest price, including Galaxy owners with 45W phones
Skip it if: You want to charge two or three devices at once. The Baseus EnerFill FC51 (#2) is the better pick.
Pros
- Near-full 45W on one device: 43.2W measured
- Built-in USB-C cable, plus USB-C and USB-A ports
- Over 50% into an iPhone 16 in 30 minutes (CNN)
- About two iPhone 16 Pro charges per fill
- Flashlight and 3-year warranty
Cons
- Drops to about 15W total with two devices
- Pass-through charging is very slow
- Paw LEDs show only rough charge levels
- Cable loop is not a real carry handle
Hands-on reviews behind this pick
- CNN Underscored
Show the verdict
Its best budget portable charger: the only pack under $40 to refill over half an iPhone 16 in 30 minutes, with a built-in USB-C cord and rough paw-print LEDs as the trade-off.
- Too Many Adapters
Show the verdict
Light, slim and close to its 45W claim with one device, it kept a phone and watch going on a seven-week hike, but multi-device and pass-through charging are painfully slow.
- HighTechDad
Show the verdict
A compact, sturdy and affordable pack whose built-in cable, three ports and fun paw indicator make daily top-ups easy, though 45W is not enough for power-hungry laptops.
2. Baseus EnerFill FC51 Bipow2 Pro Portable Charger 10,000mAh 22.5W: Best Cheap Charger for Sharing with Friends
This is the pack we'd hand around a group. It has a braided USB-C cable built into the side, plus a USB-C port and a USB-A port, so three devices charge at once, and a display shows how much is left.
Take a beach day: three friends, one umbrella and the pack doing the rounds between phones and earbuds. Tom's Guide saw it take a dead iPhone 17 to 50% in 29 minutes and full in 1 hour 32 minutes. Back home, it refills itself faster than any of the cheap packs in that test, hitting 50% in 46 minutes on a 65W adapter. The cable is rated for over 10,000 bends and doubles as a lanyard, and Baseus lists FCC and UL certification.
The downsides are weight and stamina. It's heavier than other 10,000mAh packs, and it kept an iPhone 17 at full charge for the shortest time of the 10K packs in that run. Is it worth it over the INIU? If you share, yes. If it's mostly your own phone, the INIU P41L-E2 (#1) is faster and lighter. And if you'd rather have no cable at all, the magnetic PicoGo AM41 (#3) is next.
Best for: Groups and households who share one pack and need it refilled quickly between outings
Skip it if: It's mostly your own phone and you want the fastest top-up. The INIU P41L-E2 (#1) is the better pick.
Pros
- Built-in USB-C cable doubles as a lanyard
- Charges three devices at once
- Fastest self-recharge in Tom's Guide's budget test
- Full iPhone 17 charge in 1 hour 32 minutes
- Display shows remaining charge
Cons
- Heavier than rival 10,000mAh packs
- 22.5W only on the built-in cable, one device
- Shortest sustained runtime of the 10K packs tested
Hands-on reviews behind this pick
- Tom's Guide
Show the verdict
The runner-up of five under-budget packs: a tuck-away USB-C cable plus two ports charge three devices, it recharged fastest by far, and it filled an iPhone 17 in 1:32, if a bit heavy.
- Tom's Guide (YouTube)
Show the verdict
Landed mid-pack in most tests but recharged much faster than the rest, hitting 50% in 46 minutes, and its integrated cable and percentage readout make it a handy budget pick.
3. Baseus PicoGo AM41 Ultra-Slim Magnetic Power Bank (5,000mAh): Best Slim Magnetic Charger for iPhone
If the brick-on-the-back feel of snap-on batteries puts you off, start here. The PicoGo AM41 is 0.3 inches thin and about 3.8 ounces, so it sits on a MagSafe iPhone like a thick card. Macworld drained an iPhone 16 Pro to zero and this 5,000mAh pack brought it back to 71%, a strong result for its size.
Imagine a first date with your phone in your jeans pocket at 25%. The pack stays stuck to the back all evening without a telltale bulge. ZDNET found the magnets held through a thick OtterBox Defender case, and the pack ran warm rather than hot. You get a short USB-C cable in the box, four colors and a two-year warranty.
But plan on one top-up, not a full day. Wireless charging runs at 7.5W, and ZDNET points out wireless loses up to 45% of the energy, so use the 20W USB-C port when you're in a hurry. Refilling at 15W takes a couple of hours, and the soft aluminum back scuffs easily. Is it enough? For an evening top-up on an iPhone, yes. If you need two full charges, the INIU P41L-E2 (#1) holds about twice as much.
Best for: iPhone owners who want a snap-on pack they barely notice in a pocket
Skip it if: You need more than one top-up from a pack. The INIU P41L-E2 (#1) holds about two iPhone charges, so it's the better pick.
Pros
- Thinner than most magnetic packs at 0.3 in
- Ultra light at about 3.8 oz
- Took a dead iPhone 16 Pro to 71% (Macworld)
- Strong magnets hold through thick cases
- Stays cool during wireless charging
Cons
- 5,000mAh is roughly one phone top-up
- Slow 15W self-recharge
- Aluminum back scratches and dents
- No way to clip the included cable on
Hands-on reviews behind this pick
MacworldShow the verdict
A sweet spot of size and stamina: the 5K ties the lightest magnetic pack Macworld has tested and beat a rival in its recharge test, though its wireless charging tops out at 7.5W.
- ZDNET
Show the verdict
The thinnest, lightest magnetic pack the reviewer has tried: it grips through a thick case and stays cool, but 5,000mAh doesn't go far and the soft aluminum back scratches easily.
4. VEEKTOMX Portable Charger 10,000mAh with Built-In Cables and AC Plug (VT105): Best Charger for Lightning and USB-C Phones
This is the pack for a family that hasn't settled on one plug. It has a Lightning cable and a combined USB-C/Micro-USB cable built in, plus USB-C and USB-A ports, so up to four devices charge at once. Fold-out wall prongs mean you refill it straight from an outlet, no brick needed.
On a family road trip, that means Grandma's Lightning iPhone, the kids' USB-C phones and an old Micro-USB gadget all feed from one pack in the back seat. Tom's Guide found it held an iPhone 17 at 100% for 5 hours 20 minutes, second best of five, with about 44% left after one full charge. At the motel, plug it into the wall with a phone attached and pass-through charging keeps both going. It weighs 8 ounces and comes with a one-year warranty.
Speed is the trade. At about 12W, a dead iPhone 17 took 2 hours 19 minutes to fill, and the pack needs over 3.5 hours to refill itself. The Hook Up also got only 81% of the energy on its label. Would we carry it? For mixed connectors, yes. If every phone at home is USB-C, the Baseus EnerFill FC51 (#2) charges much faster.
Best for: Mixed households with older Lightning iPhones and newer USB-C phones who want one pack and no brick
Skip it if: Every phone in your house is USB-C and you want quicker charging. The Baseus EnerFill FC51 (#2) is the better pick.
Pros
- Built-in cables cover Lightning, USB-C and Micro-USB
- Fold-out AC prongs, no charging brick needed
- Held an iPhone 17 at 100% for 5h20m (Tom's Guide)
- Pass-through charging while plugged into the wall
Cons
- Slowest of five in Tom's Guide test, 2h19m to full
- Recharging the pack took over 3.5 hours
- Gave only 81% of rated capacity in Hook Up test
- Heavier than plain 10,000mAh packs at 8 oz

- Tom's Guide
Show the verdict
Tom's Guide calls it the Swiss Army knife of its five cheap packs: every cable built in and AC prongs, solid 5h20m of phone support, but its 12W ceiling makes it the slowest charger.
- The Hook Up
Show the verdict
The Hook Up found it near identical to the VEGER and Charmast AC-plug banks with decent pass-through, but it gave just 30Wh, 81% of rated, so the Charmast was the better pick.
- Tom's Guide (YouTube)
Show the verdict
In the video version of the test it was slowest in every charging step and took over 3.5 hours to refill, yet it was judged reliable for a long charge with handy built-in AC plug and cables.
5. LISEN Ultra Slim MagSafe Power Bank 5,000mAh: Best Lightweight Charger for iPhone Commuters
For a light top-up on the way to work, this is the simplest snap-on pack here. It's 0.38 inches thin and about 3.6 ounces, wrapped in aluminum, and it clicks onto MagSafe iPhones from the 12 to the 18.
It earns its place at 8 a.m. on a packed bus, standing with your phone at 30%. Snap it on and keep scrolling with nothing hanging off the phone. Got a seat and a free hand? Plug in the short USB-C cable from the box instead: wired, it took an iPhone 17 to 25% in 16 minutes and 50% in 34 minutes for Tom's Guide. The magnetic link is only 7.5W, and iOS flags it as slow charging.
Stamina is the weak spot. It ran out at 79% on a dead iPhone 17 and lasted the shortest of five packs in that stamina run. It slides on a Galaxy S25 Ultra, so it's an iPhone pack. Check the listing says model 2E421, since LISEN sells newer Qi2 versions too. As a commuter top-up, we'd take it. For a thinner pack that grips through thick cases, the Baseus PicoGo AM41 (#3) is the better pick.
Best for: iPhone commuters who want a light snap-on pack for the ride to or from work
Skip it if: You want more charge from a snap-on pack and a grip that holds through a thick case. The Baseus PicoGo AM41 (#3) is the better pick.
Pros
- Only magnetic pack in Tom's Guide's budget-pack test
- Very thin and light at 0.38 in and 3.6 oz
- USB-C port charges faster when wired
- Premium-feeling aluminum build
Cons
- 5,000mAh got a dead iPhone 17 only to 79%
- Shortest stamina of five in Tom's Guide test
- 7.5W wireless; iPhone flags it as slow charging
- Weaker magnetic hold on Android phones

Tom's Guide finds it the only magnetic snap-on option in its cheap-pack test and worth it for wireless convenience, though its small 5,000mAh battery finished last on stamina.

The video calls it probably the best MagSafe pack at its price, but warns that its gains are modest: it held 100% for 3h11m and ran dry at 79% charging a dead iPhone 17.
Best portable chargers under $25 buying guide for 2027
How fast can a portable charger under $25 charge a phone?
Fast enough to matter, if you pick one built for speed. The INIU P41L-E2 (#1) is the standout: close to 45W from one port, with over half a dead iPhone 16 back in 30 minutes. The Baseus EnerFill FC51 (#2) is next, taking a dead iPhone 17 to 50% in 29 minutes.
Below that, cheap packs slow down fast. The Veektomx (#4) runs at about 12W, so a full iPhone 17 charge took 2 hours 19 minutes. And the two magnetic picks charge at 7.5W over magnets, faster only when you plug in their USB-C cable.
One trap: the speed on the box is for a single device. The INIU falls to about 15W total once a second device joins, so if you charge two phones at once, expect both to slow down.
How much capacity does a cheap power bank really give?
Plan on about two phone charges from 10,000mAh and one top-up from 5,000mAh. The INIU P41L-E2 (#1) gave about 2.1 iPhone 16 Pro charges, and the Veektomx (#4) still had about 44% left after filling a dead iPhone 17.
That's less than the label suggests, because some energy is lost as heat on the way to your phone. The Hook Up got only 81% of the energy on the Veektomx's label. Magnetic charging loses more: the PicoGo AM41 (#3) brought a dead iPhone 16 Pro back to 71%, and the LISEN (#5) ran out at 79% on an iPhone 17.
So a 5,000mAh snap-on pack gets you through an evening, not a weekend away. If you need several charges or a laptop top-up, we rank the best power banks at any price separately.
Are built-in cables worth it on a cheap portable charger?
Yes, if you've ever pulled a pack out of your bag and found no cord with it. Three picks here have one. The INIU P41L-E2 (#1) and the Baseus EnerFill FC51 (#2) have a USB-C cable built in, and the Baseus's braided cord is rated for over 10,000 bends and doubles as a lanyard.
The Veektomx (#4) goes furthest, with Lightning and USB-C/Micro-USB cables plus fold-out wall prongs, so you don't pack a brick either. The trade is weight: at 8 ounces it's the heaviest pick here.
Every pack still needs a wall charger to refill, and an old, slow phone cube makes even a fast pack crawl. If yours is due for an upgrade, pick one from our full charger roundup.
Are cheap magnetic portable chargers worth it for an iPhone?
They are for short top-ups, as long as you know the limits. The Baseus PicoGo AM41 (#3) and the LISEN Ultra Slim (#5) both snap onto MagSafe iPhones, so you can keep using the phone with no cable hanging off it.
Both charge at 7.5W over magnets, and iOS flags the LISEN as slow charging. Wireless also wastes energy, up to 45% by ZDNET's estimate, so plug in the USB-C cable when you're short on time. Grip differs too: the PicoGo held through a thick OtterBox Defender case, while the LISEN wants a MagSafe case or no case, and it slides on a Galaxy S25 Ultra.
We'd pick the PicoGo for most iPhones. For faster Qi2 magnetic charging, more capacity or a big-name pack like Anker's Nano 5K, which sits just over the cap, see what stepping up to under $50 gets you in a power bank.
How do you tell if a cheap power bank is safe?
Check three things before you buy: certifications, protections and the warranty. The Baseus EnerFill FC51 (#2) lists FCC, UL and TUV certification. The Veektomx (#4) lists ETL and FCC marks plus overcharge, overcurrent and overheating protection, and the LISEN (#5) uses temperature control to manage heat.
Warranty length tells you how much a brand stands behind the cell. INIU gives the P41L-E2 (#1) three years, the PicoGo and LISEN get two, and the Veektomx gets one.
Then check the model number against the CPSC recall list. INIU's recalled pack was the BI-B41, a different model from the P41L-E2, and Baseus's was the BS-30KP365. A pack that runs warm while charging is normal. One that gets hot, swells or smells should go to a battery recycler, not back in your bag.
Best portable chargers under $25: frequently asked questions
What is the best portable charger under $25?
We'd buy the INIU P41L-E2. It charges close to 45W from one port, puts over half a charge into a dead iPhone 16 in 30 minutes, has a built-in USB-C cable and comes with a 3-year warranty. If you'll share it with friends, the Baseus EnerFill FC51 charges three devices at once.
Are cheap power banks safe to use?
Yes, if you buy a known model with listed certifications and check it isn't recalled. The Baseus EnerFill FC51 lists FCC, UL and TUV certification, the Veektomx has overcharge and overheating protection, and the INIU P41L-E2 has a 3-year warranty. None is the recalled INIU BI-B41 or Baseus BS-30KP365.
How many phone charges does a 5,000mAh or 10,000mAh power bank give?
A 10,000mAh pack gives about two phone charges: the INIU P41L-E2 managed about 2.1 iPhone 16 Pro charges. A 5,000mAh pack gives most of one, as the PicoGo AM41 brought a dead iPhone 16 Pro to 71%. For more than one charge, get a 10,000mAh pick.
Is a power bank under $25 fast enough for an iPhone or Samsung Galaxy?
The right one is. The INIU P41L-E2 put over half a charge into a dead iPhone 16 and 70% into a Galaxy S25 Ultra in 30 minutes. The Baseus EnerFill FC51 took an iPhone 17 to 50% in 29 minutes. Avoid the Veektomx if speed matters: it runs at about 12W.
Do cheap magnetic power banks work with iPhone?
Yes, with MagSafe iPhones from the 12 on, but charging is slow at 7.5W over magnets. The Baseus PicoGo AM41 is our pick: 0.3 inches thin, it grips through a thick case and brought a dead iPhone 16 Pro to 71%. The LISEN Ultra Slim needs a MagSafe case or no case.
