Can a 65W GaN Charger Power a MacBook Pro and Phone Together

Quick answer

Yes, a 65W GaN charger can power a MacBook Pro and a phone at the same time, but the laptop will charge slower than with a dedicated higher-wattage charger. For light use while charging, this setup works fine. For heavy tasks like video editing, you'll want a 100W charger instead.

How Power Sharing Works on a 65W GaN Charger

A 65W GaN charger has a total power budget of 65 watts. When you plug in two devices, the charger dynamically splits that wattage between the ports. Typically, the first device connected gets priority, and the second device receives the remaining power. For example, a MacBook Pro may draw 45W while the phone gets 20W, or 20W to the laptop and 45W to the phone, depending on the charger's design and the devices' requests.

The Supertiny 65W GaN Charger, for instance, uses a single USB-C port that delivers the full 65W to one device. If you need to charge two devices at once, you'll need a charger with multiple ports, like the Essential GaN Charger 100W, which has two USB-C PD 3.0 ports and can split power more flexibly.

Real-World Performance: MacBook Pro and iPhone Together

When charging a MacBook Pro (13-inch or 14-inch) and an iPhone simultaneously with a 65W charger, expect the MacBook to charge at around 35-45W and the iPhone at 15-20W. This is enough to slowly top up the laptop during light use (web browsing, email) and charge the phone at standard speed. The MacBook will not charge at full speed, but it won't drain either if you're not pushing the CPU hard.

If you're editing video, running virtual machines, or gaming on the MacBook, the combined draw may exceed what the charger can supply, causing the laptop to slowly lose battery even while plugged in. In that scenario, a 100W GaN charger is a better fit.

When a 65W Charger Isn't Enough

A 65W charger is insufficient when you need to fast-charge both devices simultaneously, or when the MacBook Pro is a 16-inch model that requires 96W or more for full-speed charging. Also, if you have additional devices like a tablet or external drive, the 65W budget gets stretched too thin.

For those cases, consider the Essential GaN Charger 100W. It offers 100W total power, dual USB-C PD 3.0 ports (each capable of 100W alone), and an extra USB-C and USB-A port. This gives you enough headroom to charge a 16-inch MacBook Pro at full speed while also powering a phone and a tablet.

Diagnosis: Is a 65W GaN Charger Right for You?

• Symptom: You want to charge a MacBook Pro and phone at the same time with one compact charger.
• Likely cause: A 65W GaN charger has enough total power for both devices, but it must split the wattage. The MacBook will charge slower than with a dedicated 96W charger.
• Corrective action: Use a 65W charger with at least two ports. Connect the MacBook first to get priority power. Avoid heavy laptop tasks while charging. If you need full-speed charging for both devices, switch to a 100W GaN charger.
• When to stop or choose another option: If you own a 16-inch MacBook Pro, or if you regularly edit video or run intensive software while charging, a 65W charger will not keep up. Choose a 100W charger like the Essential GaN Charger instead. For most users with a 13-inch or 14-inch MacBook Pro doing light work, a 65W charger works fine. For heavy users or 16-inch models, go with 100W.

Product facts

• Supertiny - The smallest 65W GaN Charger: Supertiny is the smallest 65W GaN charger ever, with a single USB-C port supporting Power Delivery. It delivers reliable, high-performance charging for laptops, smartphones, and tablets. Its ultra-compact size makes it ideal for travel, but the single port means you can only charge one device at a time. For multi-device charging, you'll need a charger with multiple ports.
• Essential GaN Charger - 100W power, 45% smaller: Essential GaN Charger delivers 100W total power with dual USB-C PD 3.0 ports (100W each), plus an additional USB-C (20W) and USB-A QC 3.0 (18W). It's 45% smaller than traditional chargers and features a heat-dissipating aluminum design. With 100W and multiple ports, this charger can handle a MacBook Pro and phone simultaneously at full speed, plus additional devices. It's the upgrade path if a 65W charger feels limiting.
