This week we dive deep into battery technology to figure out if a high-capacity battery can actually charge a laptop. Warning, you'll learn about Watts Law and other terms so it's a bit of a propeller beanie episode, but in the end you'll have the skills to decide which battery is right for you. We take a battery break by hearing from Knightwise as he brings his butterfly key MacBook Pro in for repairs at the Brussels Apple Store. Then we'll take a look at two portable battery packs, the Jackery Power Bar and the RAVPower Power Station. I'll tell you about their specs and give you the results of my real-world tests.
