Current HTC phones like the One M8 have solid battery life, but that won’t do you much good if you’re already running low on energy and need a top-up as soon as possible. That’s where the company’s upcoming Rapid Charger 2.0 might just come in handy. The wall adapter leans on Qualcomm’s Quick Charge 2.0 to fill your power pack up to 40 percent faster — not as useful as the Droid Turbo’s 15-minute partial boost, but enough to get you through a long night out. There are a few catches, though. You’ll have to wait a little while to get US pricing and availability, and the compatibility is limited to a handful of 2014 devices with Quick Charge 2.0 built-in. The One M8, One E8, One Remix and Desire Eye are your only options. If you’re carrying an older One or a budget phone like Desire 610, you’ll be stuck with slow charging for now.
