Last fall, DURACELL launched a pair of unique new power banks designed to look like its signature batteries. Now, they’re on sale. Amazon currently has the DURACELL M150 Power Station for $129 shipped. This drops from the usual $159 price tag and matches the all-time low. It’s only the second time we’ve seen it on sale, and it matches the launch discount from back in December. The larger M250 Power Bank shares the same DURACELL design and drops to $199 from its usual $249 going rate. This, too, matches the all-time low as only the second-ever discount.
