Today only, B&H Photo Video offers the HP Power Pack Plus 18,000mAh Portable Battery Pack Bag for $39.99 with free shipping. That's the lowest price we could find by $64, although it was $5 less in December. It charges up to three devices simultaneously via two USB Type-A ports and one USB Type-C port. It also includes a 7.4mm-to-4.5mm tip adapter and cable for charging HP laptops. (Laptop charging requires the bag be plugged in via the included power adapter.)
Start off the new year by implementing these small-but-smart savings strategies. They'll soon add up.
