Amazon offers the APC Back-UPS Connect with USB Charging ports (model BGE90M) for $39.99 with free shipping. This uninterruptible power supply (UPS) usually sells for around $65 and the only other time we’ve seen it drop this low was during Amazon’s Prime Day sale.
This APC UPS is specially tuned to keep low-power gear like your wireless router, cable modem, VoIP system, and cordless phone running for up to 4.5 hours during a power outage. What’s more, it includes a pair of USB charging ports that’ll give off juice long after your power goes down. On a daily basis this unit protects your electronics from dangerous power surges and spikes. Rated 4.1 out of 5 stars from 129 Amazon reviewers.
