HyperDrive HyperJuice 2 external battery review - Impressive MacBook, iPad compatible battery from Sanho

The HyperJuice 2 from HyperDrive is a stylish, silver battery pack, about the size of a large paperback, which will happily charge a range of devices, particularly convenient on your travels. Billed as the 'world's most advanced battery for Apple MacBook, iPad, iPhone and USB' devices, the MBP2-100 model comes with an impressive 100Wh (27,000mAh) capacity battery and two 12W USB ports. Manufactured by Sanho, a specialist in portable power and storage, the device also includes an OLED display for showing battery percentage, temperature and battery time remaining. The makers list some exceptional statistics for extending battery life, including extending MacBook battery life up to 26 hours, extending the iPad mini battery life by up to 71 hours and fully recharging the iPhone up to 19 times. Better still, you can connect your MacBook and any two iOS devices and recharge them simultaneously, and during our test period the HyperJuice 2 has performed well at keeping our Apple devices topped up with power.

Sanho note that to get the battery to work with a MacBook, users need a pre-modified Apple MagSafe Airline Adapter or Magic Box kit, which the company sells separately on their website for $49.95, or around £40 on Amazon. Depending on your MacBook model you may also need the MagSafe to MagSafe 2 adapter, which costs $10. Sanho's online HyperShop shop will also bundle the Magic Box with the HyperJuice 2 and includes a 'let us do it for you' option when ordering, along with the ability to select a UK 'AC Adapter Pin'. Various online guides offer simple advice on going down the DIY route, although it's worth noting the process irreversibly modifies your original adaptor and will void your Apple warranty. Thankfully, our review sample included the pre-modified adaptor and Magic Box kit, so we were up and running quickly and efficiently.

Weighing in at 1.3 Kg - almost 3 lbs - the HyperJuice 2 is significantly heavier then we would have hoped, especially when you take into account the addition of the power supply on your travels. The battery and power supply doesn't come with any pouch or convenient way of keeping everything safe and tidy amongst your suitcase, or travel bag, which is a pity. Sanho have once again supplied a basic manual, rather series of diagrams, to get users started, which will likely have many looking online for help, including the excellent iFixit, the online 'repair manual' anyone can edit. While the battery is replaceable, it's not clear exactly how long the battery will last, especially when you consider it's likely to be in regular use. A significant investment, it's an issue raised amongst customers on Amazon and one that Sanho might address. On the plus side, the modular design means parts of the device can be replaced or repaired, which could likely extend the life of the HyperJuice 2, a more affordable and greener option than simply replacing the unit.


The HyperJuice 2 from HyperDrive is clearly a premium priced solution for keeping your MacBook, iPad and more working on the road that won't be for everyone, but will impress those who want the reassurance of having back-up power anywhere. For those users, it's a worthy investment, one that brings peace of mind despite the price.
