How to Charge Your MacBook Without the Official Charger

It‘s a dreaded scenario every MacBook owner fears – you‘re away from home and realize you don‘t have your official Apple charger with you. Maybe you forgot to pack it for a trip, lost it while out and about, or it stopped working unexpectedly. Whatever the reason, you‘re now faced with a laptop battery that‘s quickly draining with no easy way to recharge it.

Don‘t panic! While ideally you always want to use the charger that came with your MacBook for maximum safety and performance, there are some alternative methods you can use to charge your MacBook in a pinch without the official power adapter and cable. Some require extra accessories you may already have on hand, while others make use of power sources you can find in many places.

The key is knowing what your options are, understanding the limitations and risks involved, and taking proper precautions to protect your expensive device. In this guide, I‘ll break down several ways you can charge a MacBook even if you don‘t have a standard Apple charger with you.

But first, a few important warnings:

Check the Wattage First!

Before attempting to charge your MacBook with any unofficial power source or adapter, you absolutely must check that the wattage matches or falls below your laptop‘s requirements. Feeding too much wattage into your MacBook can damage the internal components or even be a fire hazard.

You‘ll find the wattage your MacBook needs printed on the bottom of the laptop or in the technical specifications on Apple‘s website. Never use a charger that exceeds this wattage rating, even if the connectors fit.

Avoid Long-Term Use of Alternative Charging Methods

I also strongly recommend limiting your use of alternative, non-Apple chargers as much as possible. While they can work as a short-term solution, relying on them regularly can degrade your MacBook‘s battery or cause cumulative damage to the power systems over time.

Stick to the official charger whenever you can, and only use these backup methods to get through those times when you‘re caught without it temporarily. Invest in an extra official charger to keep in your travel bag if you‘re frequently on the go.

Okay, with those cautions out of the way, let‘s look at some of the best ways to charge your MacBook without Apple‘s charger:

1. Portable Battery Banks

One of the most convenient options is to use a portable battery bank. These rechargeable power bricks have become very popular for charging smartphones and tablets on the go, but many have enough capacity to charge a laptop too.

There are two main types – smaller pocket-size models designed for phones, and larger "power stations" or "super batteries" made for charging laptops. For a MacBook, you‘ll want one of the more powerful models with at least a 20,000mAh capacity and support for high-speed USB-C PD (power delivery) charging.

Some top picks for MacBook-friendly portable chargers:

• Anker 737 PowerCore 24K (24,000mAh)
• Zendure SuperTank Pro (26,800mAh)
• Mophie Powerstation USB-C XXL (19,500mAh)
• Omni 20c+ (20,000mAh)

Just make sure to fully charge up your power bank beforehand. They won‘t do you any good if they‘re dead! Get in the habit of recharging them whenever you have access to a wall outlet so they‘re always ready.

2. Solar Chargers

For off-grid adventures like camping trips, a portable solar charger can be a lifesaver. These use photovoltaic panels to convert sunlight into electricity that you can use to directly charge your MacBook or recharge a battery bank.

Like power banks, solar chargers come in a range of sizes. Smaller ones are great for phones but you‘ll need a larger model to charge a power-hungry laptop. Some well-reviewed options are:

• BigBlue 3 28W Solar Charger
• Anker 515 24W PowerPort Solar Panel
• Jackery SolarSaga 60W Solar Panel

Of course, the big limitation with solar is you need ample direct sunlight. They won‘t work well on overcast days or in a shady forest. But in the right conditions, a solar charger can keep your MacBook powered up even in the middle of nowhere.

3. USB-C Chargers

Many newer MacBooks have switched to USB-C charging, which opens up more possibilities compared to older models that used Apple‘s proprietary MagSafe chargers. If you have a USB-C MacBook, you can use a third-party USB-C charger, or even your phone‘s USB-C charging brick in a pinch.

The catch is that phone chargers tend to be much lower wattage than a MacBook typically needs. For example, an iPhone 13 Pro Max comes with a 20W USB-C charger, while a 14-inch MacBook Pro needs 67W or higher. So while a phone charger will work, it will charge your laptop much more slowly. You‘ll want to use a higher-wattage USB-C PD charger for better results.

Some good options are:

• Anker Nano II 65W
• Spigen 100W Desktop Charger
• Hyphen-X 100W 4-Port Charger
• Belkin 108W 4-Port Wall Charger

4. Universal Power Adapters

When traveling internationally, you might have your Apple charger but can‘t use it with foreign wall outlets. In that case, you just need a universal travel adapter that converts between different types of electrical sockets. These are cheap, widely available, and much easier than buying a whole separate charger.

Look for a model that‘s rated for use in the countries you‘re visiting and has built-in surge protection. Some good universal adapters for international MacBook charging:

• Epicka Universal Travel Adapter
• Zendure Passport II Pro
• Ceptics World Travel Adapter Kit

5. Car Chargers

If you spend a lot of time driving, you can take advantage of your car‘s built-in power outlets to charge your MacBook on the road. Older cars will have a 12V receptacle (aka a cigarette lighter socket) while many newer models also have standard wall-style 120V AC outlets or even USB ports.

For a 12V socket, you‘ll need a power inverter that converts the 12V DC current to 120V AC power that your MacBook charger can use. These are available in a range of wattages – for a MacBook, you‘ll usually want at least 150W. Some recommended inverters are:

• Bestek 300W Power Inverter
• Jackery Explorer 240 Portable Power Station
• Anker 521 PowerHouse 200W

If your car has a built-in AC outlet, you can just plug your Apple charger directly into that, no inverter needed. And if it has USB ports, you can connect your MacBook with a USB-C to USB-C cable for easy charging. Just note that the USB ports may charge more slowly than a wall outlet.

Stay Charged Up & Ready!

As you can see, being caught without your regular Apple charger doesn‘t have to mean being stranded with a dead MacBook. With a little advance preparation and the right accessories, you have quite a few backup charging options to keep you powered up no matter where you are.

Just remember, these alternative methods are for occasional use in a pinch, not a full-time substitute for your standard charger. Check the wattage ratings carefully and avoid using them any longer than you need to. Use official Apple chargers whenever possible to keep your MacBook battery healthy and happy for the long haul!
