Until very recently, USB-C Power Delivery battery packs were exclusively large. Like 20,000mAh or more, and a few pounds to boot. But if you don’t need that much power for a few hours on a plane, this pack from Xcentz is a svelte 10,000mAh, and only $15 today with promo code KINJA157.

To be clear, its USB-C PD port only outputs 18W, not the 30W or even 45W we’ve seen on larger packs. But I used a sample they sent with my Nintendo Switch on a flight last weekend, and it was fast enough to increase the charge level on my Nintendo Switch while playing Breath of the Wild, albeit not very quickly. It’ll also charge an iPhone at the maximum possible speed if you pair it with a USB-C to Lightning cable like this one.
