Portable power stations have expanded exponentially in popularity during the past few years, from summer camping and back-yard barbecue gatherings to winter electrical outages. A reliable backup source of power is something that anyone can benefit from and these units are demonstrating their value in all forms of use.

Anker is selling their 737 Power Bank for 30% off. If you're constantly looking for a charger, it's worth getting some backup juice.

Anker’s GaN charger (GaN chargers are smaller and less prone to overheat) has 4 USB-C ports, 2 USB-A ports, and looks like a mini alarm clock for your desk. Once again, it can get your MacBook to 50% charge in 25 minutes via USB-C.
