The fastest way: borrow a USB-C or Lightning cable and any power source
If your charger is lost or broken, the quickest solution is to use someone else's cable. iPhones from 2023 onward (iPhone 15 and newer) use USB-C, while older models use Lightning. Check which connector your phone has at the bottom, then ask to borrow the matching cable from a friend, family member, or coworker.
Once you have the cable, you can plug it into almost any power source: a laptop, a desktop computer, a wall outlet with a USB adapter, a car charger, or a power bank. Your phone will charge at whatever speed that source provides — a laptop USB port charges slower than a wall outlet, but it still works. You do not need the original Apple charger; any cable that fits your phone's port will charge it.
If you cannot borrow a cable right now, a phone repair shop, electronics store, or even a grocery store with a phone accessories section will sell replacement cables for $10 to $25. This is usually faster than waiting for delivery.
Key Takeaways
- Any USB-C cable works with iPhone 15 and newer; any Lightning cable works with iPhone 14 and older — you do not need an Apple-branded charger.
- Laptops, computers, car chargers, and power banks all charge iPhones if you have the right cable, though wall outlets charge fastest.
- Wireless charging pads work with any iPhone model from iPhone 8 onward and require no cable, though they charge more slowly than wired options.
- Public charging stations in airports, libraries, and coffee shops have cables you can borrow, but avoid leaving your phone unattended.
- A replacement cable costs $10 to $25 at most phone repair shops and electronics stores and is faster than ordering online.
Wireless charging if you have a pad or mat
If someone nearby owns a wireless charging pad, you can use it with any iPhone from iPhone 8 onward. Place your phone face-up on the pad, centered over the charging coil. You should see a small lightning bolt icon appear on your screen within a few seconds, which means charging has started.
Wireless charging is slower than plugged-in charging — it typically adds 5 to 10 percent battery per hour, compared to 15 to 25 percent per hour with a wired cable. But if you have time and access to a pad, it works without needing a cable at all. Many workplaces, libraries, and coffee shops now have wireless charging pads available for customers to use.
Charging at public locations without a personal charger
Airports, train stations, and bus terminals almost always have charging stations with USB ports and cables. Plug in, wait for your phone to show the charging symbol, and leave it there while you wait for your ride. Most of these stations are free, though some airports have paid charging lockers if you want privacy.
Libraries, community centers, and coffee shops often have outlets and may lend you a cable if you ask. Tell staff that your charger is broken or lost — most will let you borrow one for 30 minutes to an hour. Some coffee shops have cables permanently attached to tables or charging stations.
If you are in a car, ask the driver if they have a car charger. Most people with phones have one, and it takes only a few minutes to charge enough battery to make a call or send a message.
What to watch out for at public charging stations
Public USB ports and charging stations are convenient, but they are not always find. Avoid charging your phone unattended in a busy place where someone could unplug it or take it. If you must leave it, stay within sight of it or ask a trusted person to watch it.
Some public charging ports can transmit data to your phone if you connect to them. To reduce this risk, use a cable you own rather than one permanently attached to a public station, and never accept a prompt to "trust" a computer or device when you plug in. If a public station asks you to unlock your phone or enter a password, do not use it — find a different outlet.
The safest public charging option is a wall outlet with your own cable, or a wireless charging pad if one is available. These do not require you to plug into a shared device.
Charging from a computer or laptop
Any computer with a USB port can charge an iPhone if you have the right cable. Plug the Lightning or USB-C end into your phone and the other end into a USB port on the computer. Your phone will charge whether the computer is on or off, though it charges faster when the computer is powered on.
Charging from a computer is slower than a wall outlet — you will see about 5 to 15 percent battery gain per hour depending on the computer and cable. But if you are at work or school and your charger is at home, this is a practical option while you work or study.
Using a power bank if you have one
A power bank is a portable battery that stores charge and transfers it to your phone through a cable. If you own one or can borrow one, plug your phone into it the same way you would plug into a wall charger. The power bank will charge your phone until either your phone is full or the power bank runs out of stored energy.
Power banks vary widely in size and capacity. A small one might add 20 to 30 percent to your phone's battery; a larger one can fully charge your phone two or three times. If you borrow someone's power bank, ask them how much charge it has left so you know how much battery you will gain.
When to buy a replacement charger
If your charger is broken or lost and you cannot borrow one, a replacement cable costs $10 to $25 at a phone repair shop, electronics store, or big-box retailer. A wall adapter (the brick that plugs into the outlet) costs $15 to $35. Buying in person means you can charge your phone the same day instead of waiting for shipping.
If you want to order online, third-party cables and adapters are cheaper than Apple-branded ones and work just as well. Check the reviews to make sure the cable is rated for your phone model. Delivery usually takes 2 to 5 business days depending on where you order from.
Keep a spare cable at work, in your car, or at a friend's house so you always have a backup. This costs less than $20 and saves you from being stuck without a charger again.
Frequently Asked Questions
Can I charge my iPhone with an Android charger?
Only if the Android charger has a USB-C port and your iPhone is a model 15 or newer. Older iPhones use Lightning connectors, which Android phones do not use. If the Android charger has a USB-C cable, it will work with a new iPhone, but the cable itself must fit your phone's port.
Does wireless charging damage my iPhone battery?
Wireless charging is safe for your iPhone battery and does not cause damage. It charges more slowly than a wired cable, which actually means less heat and stress on the battery over time. You can use wireless charging regularly without worry.
What if I left my phone plugged in at a public charging station and forgot it?
Go back as soon as you realize it. Most public charging stations are monitored or in busy areas, so your phone is likely still there. If it is gone, contact the location's staff or security to report it. If you have Find My iPhone turned on, you can use another device to locate it.
Is it safe to charge my iPhone in a car?
Yes, car chargers are safe and widely available. They plug into your car's 12-volt outlet (the cigarette lighter socket) or USB port and charge your phone while you drive. Make sure the charger is rated for your phone model and cable type.
Can I charge my iPhone faster with a higher-wattage charger?
Your iPhone will charge as fast as it can handle, regardless of the charger's wattage. Using a higher-wattage charger will not damage your phone — it will straightforward charge at the phone's maximum speed and stop. A 20-watt charger and a 65-watt charger will both charge your iPhone at the same speed.
