Sunvalleytek via Amazon offers the RAVPower 3-port 26800mAh External Battery Pack for $79.99. Applying coupon code S88LIBCE drops the final price to $52.99 shipped. That’s $27 off the regular price and the best current offering we can find.
RAVPower’s external power bank has enough juice to fully charge a 12-inch MacBook when it is powered down, or to maintain its built-in battery levels while in use for an extended period of time. You’ll need a USB C to A cable to do so. It can also re-fuel an iPhone 6 over ten times on a single charge. Built-in LED indicators denote how much battery life is left.
