There’s no shortage of power banks you can use to recharge your phones and tablets on the road. Try to use those same batteries on your laptop, though, and you’re probably out of luck. You probably need something bigger. Something like the Voltaic V88.
No, it’s not one of those power banks you can squeeze into your pants pocket. Instead, this thing has a profile that’s closer to your laptop, which means you’ll need to keep it inside the same bag where you typically hide your productivity machine when it’s not in use.
For the hassle of lugging a near-laptop-sized battery around, though, the Voltaic V88 rewards you with enough power to fully charge most laptops in under three hours, essentially doubling the operational time you can squeeze out of the computer while you do your thing on the road. Whether you need to do a fair amount of work while camping with the family, perform inspections out in the field, or drive from spot to spot with no assurance of power outlet access, this thing makes sure you won’t ever be caught with a dying battery in the middle of finishing up a report.
It measures 8.6 x 5.4 x 0.9 inches (width x depth x thickness), so it’s not exactly the most compact backup battery, although that size does mean they managed to fit a generous 24,000 mAh Li-Polymer module inside the enclosure. Aside from charging drained laptops once to a full-charge, that large battery can also charge most smartphones up to seven times, DSLR cameras up to five times, seven-inch tablets up to four times, and 10-inch tablets up to three times. In turns, the power bank can charge from wall outlets, solar panels, and a car’s charging port.
The Voltaic V88 has an easy-to-read LED display that lets you see the battery’s real-time power levels, as well as what voltage it’s currently delivering, so you can make sure you have the right output setting for whatever device is currently plugged in (you can easily change voltage by holding down the power button). It supports pass-through charging, so you can charge the battery from an outlet while charging your laptop at the same time, while an “Always On” mode lets you keep the battery’s output at the same level for extended periods of time even when the plugged device is drawing little to no power (in the default mode, the device automatically switches off when the plugged device stops drawing power).
It has included cables for charging all smartphones and tablets, a USB-C cable (for your modern gadgets), and 10 laptop adapters for use with different brands. They also have optional adapters that you’ll need to buy separately for MagSafe, MagSafe 2, and Microsoft’s Surface laptops. According to the outfit, the power bank is in compliance with all FAA guidelines, so you can safely throw this into your carry-on luggage without any worries, too, making it ideal for travelers who carry a laptop with them at all times.
