Not all power banks are made equal. Some feature one of the most impressive designs I have ever seen with an onboard display, the ability to charge two MacBooks at once, RGB lighting, and a a pair of window cutouts in the solid metal housing to put the internal tech on display – Sharge’s new Shargeek 300 Power Bank is amazing and you should, at the very least, check this thing out while the launch deal is live. Here are some of my hands-on impressions.
