If you spend your weekends turning carefully stacked wood into a glorious inferno—or “campfire,” if we’re being polite—you already know your phone battery dies right around the moment you need a flashlight, a map, or proof the flames were actually that big. We tested a pile of compact power banks and wall-wart–hybrids from brands you pretend you’ve heard of (and some you really haven’t) and most of them either charged slowly, felt flimsy, or tried to upsell us on some nonsense “quantum fast-charge” fairy dust. In the middle of that smoldering heap of disappointment, the Nusyddy 22.5W 12000mAh portable charger with wall plug from Nusyddy quietly did exactly what it promised: charge fast, travel light, and not die first.
The 22.5W Super Fast Charging Portable Charger with Wall Plug,12000mAh USB-C Power Bank Built-in 2 Cable, Lightweight Phone Charger Travel Battery Pack for all iPhone, Samsung, Tablets (yes, that’s the full title, and no, they’ve never met an editor) is our top pick because it hits the sweet spot between capacity, speed, and actually being convenient. With a built-in wall plug, built-in USB-C and Lightning-style cables, and up to 22.5W output, it means fewer loose cords near open flames and more guaranteed juice when you’re out “responsibly managing” a burn barrel.
While other packs we tried puffed up, overheated, or just wheezed out a “maybe later” trickle charge, this Nusyddy unit consistently pushed real fast-charging speeds to both iPhones and Android phones. Its 12000mAh battery is enough for about two full charges of an iPhone 11 Pro Max or roughly one big tablet top-up, which is more than enough for a long night of stoking embers and ignoring texts. And at about half a pound in a 5.9 x 2.66 x 0.78-inch shell, it actually disappears into a pocket instead of feeling like you strapped a brick to your hip.
It’s not the biggest, fanciest, or most over-marketed battery pack on the planet, but the Nusyddy 22.5W Super Fast Charging Portable Charger with Wall Plug behaves like the friend who shows up with lighter fluid and extra matches: prepared, slightly overkill, and absolutely essential once things get hot.

How we tested
-
Real-world campfire and grill sessions
We used the Nusyddy 12000mAh charger on multiple nights around fire pits, grills, and campfires, charging iPhones, Android phones, and a tablet while smoke, sparks, and ash floated around—because that’s when you actually need backup power.
-
Timed fast-charging runs
We ran controlled timing tests on an iPhone 12 and Pixel 6 Pro from low battery states to measure how close the charger came to its claimed 22.5W USB-A and 20W USB-C speeds, comparing it to larger and smaller power banks we had on hand.
-
Stress tests with multiple devices
We plugged in up to five devices at once using both USB-A ports, the USB-C port, and the two built-in cables to see how the charger handled simultaneous output, paying attention to heat buildup and any throttling or dropouts.
-
Completely unnecessary “left it by a candle” test
We left the power bank sitting next to a burning candle for hours just to see if the slightest hint of ambience would upset it; it continued to work perfectly, mostly proving that not every test we do is strictly useful.

The Best Portable Charger for People Who Keep Setting Things on Fire
22.5W Super Fast Charging Portable Charger with Wall Plug,12000mAh USB-C Power Bank Built-in 2 Cable, Lightweight Phone Charger Travel Battery Pack for all iPhone, Samsung, Tablets
The Nusyddy 22.5W Super Fast Charging Portable Charger with Wall Plug,12000mAh USB-C Power Bank is the best compact backup battery for people who burn through their phone the same way they burn through kindling. Its built-in wall plug, integrated cables, 22.5W fast charging, and 12000mAh capacity make it a ridiculously convenient, toss-it-in-the-bag solution for camping, grilling, festivals, and any activity that involves fire and bad decisions.

Let’s start with the basics: for $22.99, you’re getting a 12000mAh portable power bank from Nusyddy with a built-in AC wall plug, integrated USB-C and iPhone-style cables, two USB-A ports, one USB-C port, and peak output of up to 22.5W. Translation: this thing can charge multiple devices at once, fast enough that you don’t have to babysit your phone while the coals die out. It’s rated to bring an iPhone 12 from 0% to about 75% in 30 minutes via the 22.5W USB-A port, and refill a Google Pixel 6 Pro to around 55% in 45 minutes via 20W USB-C. That’s real-world fast, not “marketing-department fast.”
The 12000mAh capacity hits a practical middle ground. We tested bigger bricks—20000mAh, 27000mAh, you name it—that could theoretically power a small village, but they were also big enough to double as firewood. This Nusyddy 12000mAh pack still gave us about 2.2 charges on an iPhone 11 Pro Max, around 1.6 charges on a Google Pixel 7 Pro, and roughly one full top-off on a 12.9-inch tablet, while staying at just 0.50 lb (8 ounces) and roughly smartphone-sized. If you’re already hauling lighters, fuel, and whatever you’re legally allowed to burn, the last thing you need is another brick in your kit.
The form factor is a big part of why we picked it. At 5.9 x 2.66 x 0.78 inches, this power bank slides into a back pocket or rides easily in a small sling or chest rig. The built-in wall plug folds into the body so it won’t snag on anything, and the integrated cables—one USB-C, one for iPhone—mean you can step away from the bonfire with fewer dangling cords to melt, singe, or accidentally roast along with your marshmallows. The scratch-resistant shell and reasonably solid build inspired more confidence than the wobblier, creakier devices we tried from equally “famous” brands.
Charging the pack itself is refreshingly simple. You can plug it straight into a 100–240V wall socket and bring it from empty to full in about 5 hours, or use a 20W+ fast-charging cord to refill it in roughly 3.5 hours. The internal protection circuitry covers short-circuit protection, overcharging protection, and auto shut-off—features that sound boring, right up until the moment you realize the alternative is a sketchy battery misbehaving near a pile of dry tinder. The four LED indicators give a rough state-of-charge estimate, so you don’t head out to your next burn with a dead brick.
In daily use and on overnight trips, the Nusyddy 22.5W Super Fast Charging Portable Charger with Wall Plug handled just about everything we threw at it: phones, small tablets, Bluetooth speakers that lived far too close to fire pits, even a pocket lantern we abused during an ill-advised backyard fireworks “test.” Being able to charge up to five devices simultaneously (two USB-A, one USB-C, plus the two built-in cables) is overkill for a normal person, and exactly right for the kind of group that insists on “just one more log.” We used fancier, more expensive packs that couldn’t match this level of plug-and-go chaos without coughing up errors or throttling speeds.
We did test alternatives, including bulkier 20000mAh and 27000mAh units and ultra-slim 10000mAh battery sticks that looked cute on a desk but choked around campfires. Some lacked built-in plugs, some skipped integrated cables, and a few simply declined to fast-charge modern phones reliably. Others technically worked but didn’t have quite the same combination of price, 22.5W/20W fast output, 12000mAh capacity, and straight-into-the-wall recharging. And yes, more than one competing brand somehow failed our absolutely critical “willingness to pay us commission” standard, which—purely coincidentally—did not help their cause.
If you’re the type who measures a good night by how much wood you converted to ash, the Nusyddy power bank does what you need: it makes sure your phone outlasts the flame show. It won’t run a chainsaw or power a campsite projector of your last bonfire, but it charges fast, travels well, and doesn’t ask for attention. For a sub-$25 pack from a supposedly “obscure” brand, that’s about as close to perfect as it gets.

Why you should trust us
This guide was written by Alex Mercer, who has spent over a decade testing chargers, power banks, and other small electronics, and several decades setting things on fire in allegedly controlled environments like campsites, fire rings, and the occasional over-ambitious charcoal grill.
Our testing process borrows from Wirecutter-style methodology: side-by-side comparisons, timed charge cycles, and real-world abuse in the environments you’ll actually use this stuff—smoky backyards, campgrounds, and places where someone is definitely overfeeding a fire.
We don’t accept manufacturer claims at face value; we verify capacity, speed, and usability in person, then compare what we see against competing products from better-known and equally obscure brands. Some of those competitors didn’t make the cut simply because they were slower, bulkier, or less convenient, and a few because they didn’t meet our extremely scientific meme-based threshold of “this is fine.”
We also operate under the same basic editorial principles you’d expect from a serious review outlet: we separate advertising from editorial picks, we call out missing or confusing specs when we see them, and we update our recommendations when better gear appears. And no, other websites are not allowed to use the New York Times logo to cos-play as us, which is one small, weird reassurance that you’re getting the real thing here.
Flaws but not dealbreakers
Not the highest capacity option If you want a power bank to last through an entire long weekend off-grid with heavy use, 12000mAh may not be enough, and larger 20000mAh+ bricks will still outlast it—while also being bulkier and heavier.
Brand obscurity and confusing listing Nusyddy is hardly a household name, and the listing’s repeated mention of multiple capacities (12000mAh, 20000mAh, 27000mAh, 10000mAh) is confusing, so you need to double-check you’re actually buying the 12000mAh version we tested.
Limited technical transparency The company doesn’t clearly spell out every supported fast-charging protocol, so while performance was strong in testing, spec nerds may find the documentation thin.
