Words I like: The best gear is the gear you stop thinking about. Hey ! Waterproof. Charges laptops. No one else makes both. Most people who work or travel outdoors have two power banks. A small waterproof one for their phone, and a bigger one for their laptop that they pray doesn't get wet. I know because I used to do the same thing. Wrap the laptop bank in a Ziploc, stuff it deep in the bag, and hope for the best every time I got caught in the rain or packed for a trip near water. The problem is every 20,000mAh power bank that can push 65W to a laptop is built with vents, exposed ports, or plastic housings that can't be sealed. And every power bank rated IPX8 waterproof tops out at 20W, maybe 30W. Enough for a phone, not enough for a MacBook. The Carbo 20K Gen2 is the first bank I've found that does both. IPX8 waterproof (tested to 1 metre submersion) and 65W USB-C output, which is enough to charge a MacBook Air, a Dell XPS, or a Surface Pro at full speed.
That's the main thing. But there are two more numbers worth knowing. It's 28% lighter than the competition. Most 20,000mAh 65W banks weigh around 400-450g. The Carbo 20K weighs 320g. The housing is carbon fibre (67% lighter than plastic) and magnesium alloy (38% lighter than aluminium). If you're counting grams for a trek or a flight bag, that gap is significant. It stores 22% more usable energy. The rated capacity is 67.5Wh compared to the 55Wh you get from most 20,000mAh banks. In real terms, that's roughly 4 full charges of an iPhone 17 or one full charge of a MacBook Air with juice left over. The math on weight-to-energy: Carbo 20K Gen2: 67.5Wh at 320g = 0.211 Wh per gram Typical 20K 65W bank: 55Wh at 450g = 0.122 Wh per gram Gram for gram, it carries 73% more energy. For the same weight budget in your pack, you get significantly more power. As promised, value in under a minute. If you're the type who carries one bag and expects everything in it to survive whatever the day throws at you, the Carbo 20K Gen2 is $299 on our store.
