You know the feeling. It’s mid-afternoon, you’re nowhere near home, and the battery icon has turned that particular shade of red. Maybe your phone is getting older, maybe you’re just using it for everything (maps, music, work email, the group chat that never sleeps). Either way, the fix is rarely a new phone. It’s having power where you actually are.
So let’s sort it by problem. Find the one that sounds like your day.
Anker Power Bank With Built-In Cable

The problem: you carry a phone, earbuds, a tablet and maybe a laptop, and all of them are hungry.
This is the heavy hitter. It holds enough charge for phones and tablets and puts out enough power to top up a laptop in a pinch, and the USB-C cable is built right in, so you’re never digging through a bag for the right cord. A small screen on the front shows exactly how much charge is left.
One owner who charges a work MacBook with it calls it a permanent part of his everyday carry. He also likes the pass-through charging: plug the bank into the wall overnight and charge other devices through it, like a little hub. His only note is that it’s on the heavy side, which comes with that much capacity.
Best for: Travel days and anyone who runs more than one device.
Anker Magnetic Battery Pack

The problem: you hate being tethered to a cable while you’re out.
Snap this onto the back of a MagSafe iPhone and it charges wirelessly while you keep scrolling, walking or taking photos. Anker says it can add up to about nineteen hours of extra use, which is the difference between dead at dinner and fine at midnight. It’s ideal for concerts, conventions and long event days where outlets are a fantasy.
A buyer with a small iPhone says the pack adds little enough bulk that the phone still fits in a pocket and works normally. They do point out that wired charging is faster than wireless, which is true of any pack like this.
iWalk Pocket Charger
The problem: you never remember to bring a charger, because charging gear is clunky.

Then go tiny. This stubby charger plugs straight into the bottom of your phone, no cable at all, and it’s small enough to live in a pocket, purse or backpack without you noticing the weight. Leave it in your everyday bag and forget about it until the day you really need it.
Good to know: There are iPhone and Android versions, so double-check which port your phone uses before ordering. It comes in several colors.
Extra-Long Braided Charging Cables

The problem: the outlet is behind the couch, your cable reaches the floor, and you’re scrolling while lying on the carpet.
Sometimes the battery isn’t the issue. It’s that charging is so inconvenient you skip it. Extra length means you can plug in and still use your phone from the bed, the couch or the desk chair. These cables are fast-charging and wrapped in bendable braided nylon, which holds up to daily bending and yanking far better than thin plastic cords.
You get two in a pack, and they come in a few lengths and colors. Put one by the bed and one in the living room, and charging stops being a chore.
Magnetic Wireless Charger Two-Pack

The problem: you only have one charger, and it’s always in the other room.
Two magnetic charging pads, two spots that never run dry. Each puck clicks onto the back of an iPhone and holds it securely while it charges. They come with five-foot USB-C cables plus USB-A adapters, so they work with whatever wall plug or laptop port you already have. Put one on the nightstand and one on your desk, and your phone gets topped up all day without you thinking about it.
Best for: Spreading chargers around the house or office. Available in six colors.
Anker Magnetic Charging Pad

The problem: your current charger is old, unreliable or running hot.
If you only want one charger, and you want it to just work, this plain Anker puck snaps onto an iPhone with MagSafe and charges without any fuss. No extra features, no gimmicks. One buyer switched to it after their original Apple charger kept overheating and says it works much better. It comes in two colors.
Which fix fits your day
If you run out while you’re out, carry power: the big Anker bank for long days with several devices, the magnetic pack if you hate cables, the pocket charger if you hate bulk. If you run out because you don’t charge enough at home, spread chargers around instead: longer cables where outlets are awkward, magnetic pads where you set your phone down anyway. Most people end up happiest with one of each.
