What is it? 12-hour battery life on your MacBook Air not good enough? CHUGPLUG’s got you covered! This battery pack for MacBooks can give you up to an extra four hours of battery life (depending on the model). It’s a pack that fits onto the MacBook’s power adapter, between it and the plug that goes into the wall. There are different versions for 45W and 65W power adapters. When’s it due? Get chugging now. By which we mean it’s available to buy. Why are we excited? In some ways, this is a little less slick than the HyperMac MacBook batteries that were your best option previously – it’s a big chunky stick to attach to your power adapter. However, it’s also much simpler, doesn’t involve changing any parts critical to running your laptop, and is massively cheaper. For a bit of emergency battery power, this seems like the best option right now.
