You’re on a plane, binge-watching your favorite show, but your laptop is running out of battery. With two hours left before you land, you kick yourself for not being prepared. “That’s it,” you think to yourself, “as soon as I land, I’m getting a powerful battery pack.” Well, this week’s giveaway is for you.

ZMI is giving away two powerful portable chargers valued at nearly $230 to two lucky winners. The top prize is the $149 ZMI PowerPack No. 20, which puts out a massive 210W and can recharge a 16-inch MacBook Pro and two other devices simultaneously. This good-looking battery pack won a prestigious design award from Red Dot.

Second prize is the more portable ZMI PowerPack 20K Pro, which puts out 65W max and is valued at $80. Enter this week’s giveaway for your chance at winning one of these two battery packs.

As mentioned, our first-prize winner will get the PowerPack No. 20. This 2021 Red Dot industrial design winner is the most powerful battery pack ZMI offers. It is designed for users who want a reliable power bank that charges their laptop even while it’s running power-hungry tasks like photo/video editing or gaming.

It boasts a massive 25,000 mAH capacity, which is enough to recharge an iPhone 12 up to five times, an 11-inch iPad Pro twice or a 13-inch MacBook Pro 1.3 times. It can deliver 100W over one of its USB-C ports, which means it can charge all newer MacBook Pro laptops, even the 16-incher (which will recharge up to 75% in one hour).

The PowerPack No. 20 also comes with two other high-powered ports (a second USB-C and one USB-A), so it can charge up to three devices at once. While charging your laptop, you can plug in your iPad Pro and iPhone as well. If you want to extend battery life further, it offers pass-through charging so you can recharge the battery pack while charging your MacBook Pro.

Still, it comes in under the Federal Aviation Administration’s size limit so it can be used on a plane. Plus, its built-in thermal-protection system prevents the battery pack from overheating or swelling.

Second prize in this week’s giveaway is the PowerPack 20K Pro. Smaller and lighter than the PowerPack No. 20, it fits nicely into a briefcase or handbag. The PowerPack 20K Pro puts out up to 65W and can fully recharge a 13-inch MacBook Pro, or an iPhone XS up to five times. The powerful 65W USB-C output allows you to charge a MacBook even while editing video.

It comes with two USB-A ports and one USB-C port, and also can recharge up to three devices simultaneously. It can also double as a USB hub when in “hub mode.” With it, you can attach two external USB devices to your MacBook or iPad, such as a mouse, thumb drive or hard drive. It comes with temperature, overcurrent, overvoltage and short-circuit protection.

If you’re looking for a compact yet powerful battery pack that can charge your MacBook Pro or iPad Pro, then the ZMI PowerPack 20K Pro is for you.
