Now that the weather is warming up, if you’re hoping to take your laptop out into the park but fear that your battery won’t last long, what you need is a reliable high-capacity power bank. This 25,000mAh Anker Laptop Power Bank is exactly what the doctor ordered.

Built to sustain your laptop for hours, Anker’s laptop power bank has a large 25,000mAh capacity, which should be more than enough to recharge your laptop at least one full time. That alone is worth the price of admission, and it’s still within TSA’s limit for Lithium-ion batteries—you can put it in your carry-on and fly with it, no questions asked.

What’s even greater about this portable charger is that it has two built-in USB-C cables (so you don’t have to pack any cables with you) as well as separate USB-C and USB-A ports (so you can charge up to four devices at once if you ever need to). Any of those USB-C connections can hit 100W when used alone, which means it can keep your laptop charged even while you’re using it. When all four ports are in use, the main built-in USB-C cable retains its 100W speed while the others drop to 30W total.

This power bank has a smart digital display that tells you everything you need about charging speed to each port, temperature, and health. It’s compatible with any device that charges via USB. It’s a versatile little thing that’s not just great for laptops. Get it for $96 (was $135) with this limited-supply deal at Amazon—17% claimed as of this writing.
