There’s no such thing as too much battery life… but if there was, the folks at HyperJuice would be on a mission to prove it. The company makes external battery packs that you can use to charge a phone, tablet, or Apple laptop.

The biggest model is a 61,000mAh, 222Wh battery which can extend the run time of a MacBook by up to 53 hours, recharge an iPhone 40 times, or give you up to 136 hours of extra battery life on an iPad mini.

HyperJuice was showing off its wares at CES, and the idea of being able to run a laptop non-stop for more than two days without charging kind of grabbed my attention.

Unfortunately, that kind of battery life doesn’t come cheap. The 222Wh battery sells for $450.

HyperJuice does sell cheaper, lower capacity batteries for $170 and up. They offer 60Wh to 160Wh of extra power.

Unfortunately some of the company’s products get poor reviews from customers on Amazon, who complain that the batteries have poor build quality. But that’s OK. You probably didn’t want to lug around a 3.5 pound battery anyway.

HyperJuice batteries are designed to work with any device that charges via USB, but as far as laptops it’ll only work with MacBooks.

  1. $240 worth of 18650 batteries in a case….
    From a company known for poor quality.

  4. Why does anyone need 52 hours of battery life anyway?
    Are you going to stay awake working/playing that long? If Yes put down that pipe.
    Why not charge your device if/when you might sleep?

    1. Maybe if you’re going camping for a week without any electricity. Or maybe a expedition in to the rainforest…

      1. 53 hours is 2 â…“ days better have 3 or 4 of them for a week in the rain forest. The image is the Four Seasons Hotel Seoul and they have plenty of electricity to power all your devices.

  5. Hopefully fuel cells will solve the power problem, that is, if they are available soon.

    1. Fuel cells eye supposed to be the answer like 20 years ago.
      WTH happened?

      1. Fuel cells were probably killed or delayed substantially by the possibility they could be used to blow up a plane, or that fuel cell powered vehicles might explode in a crash or accidentally combust when striking road debris like recent Teslas.

        Honda had a fuel cell-equipped vehicle for a while, called the FCV-1 or soething like that. There are public transit buses running on compressed natural gas or maybe even hydrogen (the fuel in fuel cells).

        What eventually became the Chevy Volt started out as a fuel cell vehicle. I thinnk the story here is similar to electric cars. (Aside: GM leased an electric car in the 1990s, then took them all back and destroyed them, in a show of corporate stupidity. There was even a documentary, “What Happened to the Electric Car?” No wonder GM needed a bailout.)

        Toshiba or someone came out with a prototype small fuel cell, which one could carry
        safely onto an airline (this was prior to the TSA cracking down on liquids). I believe this fuel cell could power a laptop for up to 8 hours, and might have been a bit bigger than a lipstick, and weighed less than 1 lb. The burner was perhaps the size of an external DVD drive.

      2. Lots of things, Fuel cells still have their limitations… Fuel efficiency was one of the first issues, along with costs and the question of how you were going to refuel… There are many choices in fuels but a ecosystem has to be established to support any devices running on fuel cells or they’d never be practical for everyday use.

        There was also safety and portability that needed to be improved… took a long time… and then there was the annoying part of being able to turn the process on and off… Otherwise, the system would just run constantly and unless you needed power all the time then that quickly becomes wasteful…

        And of course there was politics and invested interest in existing energy sources slowing it all down… So, the years went by pretty quick before we saw any real progress and they’re likely still another decade away before we’ll see more than the occasional niche products, like camping gear, offered…

  6. That is a lot of money and a lot of weight to lug around, but it still looks like it solves some power problems for some folks.
    Luckily for the manufacturer they are catering to folks already accustomed to paying premiums for their accessories, ey? 😉
