What to use when you don't have the official charger
You can charge an iPad with any USB-C cable and power adapter that meets Apple's power requirements, or through a computer's USB port, or by borrowing a compatible charger from another device. The method depends on what you have available and how quickly you need the battery to recover.
Modern iPads use either USB-C (iPad Pro, iPad Air, iPad, iPad mini from 2022 onward) or Lightning connectors (older models). Knowing which port your iPad has is the first step, because the wrong cable won't fit at all.
Key Takeaways
- USB-C iPads can charge from any USB-C power adapter rated 20 watts or higher, including chargers from phones, laptops, and third-party manufacturers.
- Lightning iPads need a USB-A to Lightning cable paired with any standard USB power adapter, or you can borrow a charger from an iPhone 8 or older.
- Connecting your iPad to a computer via USB cable will charge it slowly but will work if no wall outlet is available.
- Avoid chargers under 10 watts for regular charging, as they may charge slower than your iPad drains power during use.
Using a USB-C charger from another device
If your iPad has a USB-C port (the flat, oval-shaped connector), you can use any USB-C power adapter you already own. Phone chargers, laptop chargers, and third-party iPad chargers all work as long as the adapter is rated for at least 20 watts. A 30-watt, 45-watt, or higher adapter will charge faster without damaging the battery.
Check the wattage printed on the power brick itself or on the cable near the connector. If you don't see a number, look up your device model online — most modern phone and laptop chargers are 20 watts or higher. straightforward plug the USB-C cable into your iPad and the adapter into the wall outlet.
If you have a USB-C cable but no power adapter, you can borrow one from a laptop charger, a newer Android phone charger, or a friend's iPad charger. The cable and adapter don't have to be from the same manufacturer.
Using a Lightning charger for older iPads
If your iPad has a Lightning port (the small rectangular connector with eight pins), you need a USB-A to Lightning cable paired with a standard USB power adapter. These are the same cables and adapters used by iPhones 8 and earlier, so you may already have one in a drawer.
Any USB power adapter rated 5 watts or higher will work. This includes the small cube adapters that came with older iPhones, iPad chargers from any brand, and most phone chargers made before 2020. Plug the Lightning end into your iPad and the USB end into the power adapter, then plug the adapter into the wall.
If you have a Lightning cable but no power adapter, you can use a charger from an iPhone 8, iPhone 7, iPhone 6, or any older iPhone model. You can also borrow from a friend's iPad charger — the adapter itself doesn't care whether it's powering an iPad or a phone.
Charging through a computer USB port
You can charge your iPad by connecting it to a computer with the appropriate cable (USB-C to USB-C for newer iPads, or USB-A to Lightning for older ones). The computer must be powered on and awake — a sleeping computer may not charge your iPad, or will charge it very slowly.
This method is much slower than wall charging because computer USB ports typically provide only 5 watts of power. A full charge may take 8 to 12 hours instead of 2 to 4 hours. Use this option only when a wall outlet is not available or when you need to charge overnight.
If your computer has a USB-C port, you can also use a USB-C to USB-C cable directly, which may charge slightly faster than a standard USB port. Check your computer's manual or manufacturer website to confirm which ports support charging.
What to avoid when charging without the original charger
Do not use chargers rated below 10 watts for regular charging. While they will technically charge your iPad, they may charge slower than your iPad uses power when the screen is on, meaning the battery will drain even while plugged in. This is frustrating but not dangerous.
Avoid chargers with damaged cables, frayed wires, or loose connections. A faulty charger can overheat and damage the battery or the iPad itself. If you're borrowing a charger, inspect it first — if it looks worn or feels hot to the touch, use a different one.
Do not use chargers designed for other devices if you're unsure of the wattage. For example, some older phone chargers are only 5 watts, which will charge an iPad very slowly. When in doubt, ask the device owner or look up the specifications online before plugging in.
Finding the right charger if you need to buy one
If you need a new charger, you have two options: buy from Apple or buy from a third-party manufacturer. Apple chargers are more expensive but may provide to work. Third-party chargers are cheaper and work just as well if you buy from a reputable brand.
For USB-C iPads, look for a charger rated 20 watts or higher. For Lightning iPads, any standard USB power adapter will work, but 12 watts or higher is ideal. Check the product listing to confirm it matches your iPad's connector type.
If you're buying online, read the reviews to confirm the charger works with your specific iPad model. Some third-party chargers are designed for phones and may not deliver enough power for an iPad, even if the connector fits.
Frequently Asked Questions
Can I use a phone charger to charge my iPad?
Yes, if the connector matches your iPad. A USB-C phone charger works with USB-C iPads. A Lightning phone charger (from iPhone 8 or older) works with Lightning iPads. The wattage should be at least 10 watts for reasonable charging speed, though any wattage will work in a pinch.
Will using a higher wattage charger damage my iPad battery?
No. Your iPad has built-in circuitry that limits how much power it draws, regardless of the charger's maximum wattage. A 45-watt charger will charge your iPad no faster or slower than a 20-watt charger — the iPad only takes what it needs. Higher wattage is safe and straightforward gives you flexibility.
How long does it take to charge an iPad through a computer?
Typically 8 to 12 hours for a full charge, depending on the computer's USB port type and whether the computer is actively in use. If you're using the iPad while it charges, the process takes even longer. Wall charging is much faster — usually 2 to 4 hours depending on the charger wattage.
What if my iPad won't charge with a borrowed charger?
First, confirm the connector type matches — USB-C to USB-C, or Lightning to Lightning. Then try a different outlet to rule out a dead wall socket. If the charger works with other devices, the problem may be a damaged charging port on your iPad, which requires service from Apple or a repair shop.
Can I charge my iPad with a wireless charger?
No. iPads do not support wireless charging. Only wired chargers — either through USB-C or Lightning — will work. If you see a wireless charger marketed for iPads, it is designed for a different product or is not a legitimate charger.
