With the cost of high capacity micro SD cards plummeting, there is no longer any reason to run out of storage space during a day filming with your GoPro. However, battery life is increasingly an issue. For example, the GoPro Hero 3+ Black already claims a battery life of only 1 hr 30 min when shooting 1080p at 60fps – and that’s under optimum conditions, with a new battery and no use of the wifi connectivity. Factor in a cold day on the ski slopes, with a battery that has been through a few charge / discharge cycles, and the actual recording time is likely to be significantly lower than this.
Managing battery life is always something of a dilemma – you want to keep the camera rolling to capture any exciting (or amusing!) action that does occur, while not blowing all your battery juice on the first coupe of hours, leaving nothing for the remainder of the day. GoPro will sell you a spare battery – but it charges nearly $20, and in order to charge it you need to swap it into the camera unit.
However, help is now at hand in the shape of the Wasabi Power Battery and dual Charger pack. This pack contains 2 spare GoPro Hero 3+ batteries, and a a double slot external charging unit which can be run either of mains power or from a car 12 volt socket. Both the wall and the car charger can also be used to charge other USB devices such as smartphones and tablets – to this end each has a 1 amp and a 2.1 amp USB port. The 1 amp connection is fine for smartphones, while the 2.1 amp is needed for larger capacity batteries like those found in an iPad. Either can be used to power the GoPro battery charging unit, but the best performance is obviously from the 2.1 amp socket. Wasabi also make a kit with just a single slot charger, though this lacks the ability to charge other USB devices.
