What to do right now if your charger is missing or broken

If your iPhone battery is low and your charger is nowhere to be found, you have four real options: borrow a compatible cable and power adapter, use a USB-C to Lightning cable with any USB-C power source, charge through a computer or laptop, or use a portable battery pack. The fastest route depends on what devices are around you and how much battery you have left.

The most important thing to know first: not every cable works with every iPhone. iPhones made before 2023 use Lightning connectors. iPhone 15 and newer use USB-C. If you grab the wrong cable, nothing will happen — it straightforward won't fit. Knowing which connector your phone has saves you time when you're borrowing from someone else.

Key Takeaways

  • iPhones before 2023 use Lightning connectors; iPhone 15 and newer use USB-C, so check your phone's port before borrowing a cable.
  • A USB-C to Lightning cable works with older iPhones if you have access to any USB-C power adapter, even from a laptop or tablet.
  • Charging through a computer takes longer than a wall outlet but works in a pinch and requires only a compatible cable.
  • Portable battery packs are the most reliable backup if you're away from outlets, but they need to be charged themselves beforehand.
  • Wireless charging pads work with most iPhones but require the pad to be plugged in, so they don't solve the problem of a missing charger.

Borrowing a cable and adapter from someone nearby

This is the fastest solution if you're at home, at work, or around people with iPhones. Look for someone with the same iPhone generation as yours — they'll have the matching connector. If your phone uses Lightning, ask for a Lightning to USB-A cable and a USB power adapter. If you have iPhone 15 or newer, ask for a USB-C to USB-C cable and a USB-C power adapter.

If you're borrowing from someone with a different iPhone generation, check the connector type before you take the cable. A Lightning cable won't fit a USB-C port and vice versa. Many households now have multiple USB-C adapters because they're standard on newer phones, laptops, and tablets, so even if the person doesn't have an iPhone 15, they may still have a USB-C adapter you can use.

Using a USB-C to Lightning cable if you have one

If you own a USB-C to Lightning cable but your charger's power adapter is missing, you can charge your phone using any USB-C power source. This includes USB-C adapters from laptops, tablets, monitors, or even some desk lamps. The cable connects your iPhone to the adapter, and the adapter plugs into the wall outlet.

USB-C to Lightning cables are less common than standard Lightning cables, but they're becoming more available as older iPhones are replaced. If you don't own one, you can purchase one at most electronics retailers or online. The cable itself costs between $15 and $25 depending on the brand and length.

Charging through a computer or laptop

Any computer or laptop with a USB port can charge an iPhone, though it charges much more slowly than a wall outlet. Plug your Lightning or USB-C cable into a USB port on the computer, then plug the other end into your iPhone. The computer must be powered on or plugged in for this to work — a laptop running on battery will charge your phone but will drain its own battery faster.

This method is useful if you're at an office, library, or school where computers are available. Charging through USB takes roughly three to four times longer than charging through a wall outlet, so if your battery is critically low, this is a backup plan rather than a primary solution. If you need your phone charged quickly, use a wall outlet instead.

Using a portable battery pack

A portable battery pack (also called a power bank) is a small device that stores electrical charge and can charge your phone anywhere. You plug your cable into the battery pack instead of a wall outlet. Battery packs come in different sizes and capacities — smaller ones fit in a pocket, while larger ones can charge a phone multiple times before needing to be recharged themselves.

The catch is that the battery pack must already be charged. If you don't own one, you'll need to purchase it and charge it at home before you can use it away from outlets. Battery packs range from $15 for basic models to $100 or more for high-capacity versions. If you travel frequently or work away from outlets, owning one is worth the investment because it solves the problem permanently.

Wireless charging pads as a temporary solution

If you have access to a wireless charging pad, most iPhones can charge on it without a cable. You straightforward place your phone on the pad, and charging begins. However, the wireless charging pad itself must be plugged into a wall outlet or power source, so this only solves your problem if the pad is already set up somewhere you can reach it.

Wireless charging is slower than wired charging — it typically takes 30 to 50 percent longer. If your phone is at 1 percent battery, wireless charging may not be fast enough to get you through the day. It's most useful as a backup option if you're staying in one place, like at a friend's house or office, where a pad is already available and plugged in.

What not to do when your charger is missing

Avoid using counterfeit or heavily damaged cables, even if they fit your phone's port. A frayed cable or one from an unknown source can damage your phone's battery or charging port over time. If a borrowed cable looks worn or damaged, ask for a different one.

Do not attempt to charge your phone through unconventional methods like car cigarette lighters without a proper car charger, or through DIY solutions involving batteries and wires. These can permanently damage your phone's battery or charging port. Stick to standard cables, adapters, and power sources.

Frequently Asked Questions

Can I charge my iPhone with an Android charger?

Only if the Android charger uses USB-C and your iPhone is model 15 or newer. Older iPhones use Lightning connectors, which Android phones don't use. Even if the power output is the same, the physical connector won't fit.

How long does it take to charge an iPhone through a computer?

Charging through a computer's USB port takes roughly three to four hours for a full charge, compared to one to two hours through a wall outlet. The speed depends on the computer's USB version and whether the computer is plugged in or running on battery.

Will charging my iPhone in unusual ways damage the battery?

One-time charging through a computer or borrowed adapter won't damage your battery. Repeated use of damaged cables, counterfeit adapters, or extreme heat can shorten battery lifespan over months or years. For occasional emergency charging, standard methods are safe.

What's the difference between USB-A and USB-C?

USB-A is the older, rectangular connector found on many older devices and wall adapters. USB-C is the newer, smaller oval connector. iPhones before 2023 used Lightning (Apple's own connector), while iPhone 15 and newer use USB-C to match other devices.

Can I charge my iPhone wirelessly if I don't have a charger?

Only if you have access to a wireless charging pad that's already plugged into a power outlet. The pad itself needs to be connected to electricity, so this doesn't solve the problem of a missing charger unless the pad is available where you are.
