In the battle for battery virility, Hyper just launched HyperJuice. The company says it’s “the world’s most powerful USB-C battery pack” and the first to support the 100W USB-C Power Delivery 3.0 Profile. The battery is capable of 130W of total combined output when using the 100W (max) USB-C input / output jack, the 60W (max) USB-C jack, and the trusty 18W (max) USB-A Quick Charge jack. And at 100Wh (27,000mAh), it’s the highest-capacity battery approved by the FAA for your carry-on luggage.

If you own a 100W USB-C charger, then you can charge the HyperJuice in about an hour. A 60W charger will take around 1.7 hours to go from empty to full. Whatever you use, you’ll have to supply it yourself since Hyper doesn’t include a charger in the box.

Notably, the HyperJuice battery can be charged while simultaneously charging all the devices plugged into it.

A note on crowdfunding: Crowdfunding is a chaotic field by nature: companies looking for funding tend to make big promises. According to a study run by Kickstarter in 2015, roughly 1 in 10 “successful” products that reach their funding goals fail to actually deliver rewards. Of the ones that do deliver, delays, missed deadlines, or overpromised ideas mean that there’s often disappointment in store for those products that do get done. The best defense is to use your best judgment. Ask yourself: does the product look legitimate? Is the company making outlandish claims? Is there a working prototype? Does the company mention existing plans to manufacture and ship finished products? Has it completed a Kickstarter before? And remember: you’re not necessarily buying a product when you back it on a crowdfunding site.

Hyper recently demonstrated a prototype battery charging a 15-inch MacBook Pro at 100W and a 13-inch MacBook Pro at 60W while simultaneously charging an iPhone X at 18W. It also demonstrated pass-through charging.

HyperJuice is launching on Kickstarter today at $149 for early bird pledges. That’s 50 percent off the expected retail price of $299, according to the company, with delivery expected in November.

The Hyper by Sanho corporation has been around for years, primarily building Apple accessories, including some of the original MagSafe-compatible batteries for MacBooks. Hyper is using crowdfunding to gauge interest in its latest product, as it has multiple times in the past to successfully raise millions. In other words, there’s risk in backing its latest venture, but it’s relatively low compared to many other high-tech campaigns.
