This Anker magnetic power bank is on sale for $20 during the Amazon Spring Sale

Anker power banks and other charging gear have been discounted thanks to the Amazon Spring Sale. Noteworthy among the deals is this Anker 321 MagGo power bank that's going for only $20 for Prime members. The discount applies to all colorways, too, including white, black, pink, green and purple.

Anker devices are some of our favorites and a few of them have made it onto our list of the best power banks and portable chargers. This particular model on sale is MagSafe-compatible, so it will magnetically attach to the back of your iPhone when you need a power-up. It's also compatible with MagSafe iPhone cases, too. Inside, there’s a 5,000mAh battery that provides up to 19 hours of additional use for modern iPhones.

It’s equipped with heat sensors that continuously monitor temperatures to avoid accidental damage and it can juice up a phone while it’s being charged itself. This power bank is also on the smaller side, so it easily fits into pockets, bags and purses.

The only downside is that this is only for Prime members. However, the Anker Nano 3-in-1 portable charger is on sale for everyone. This non-magnetic charger includes a large 10,000mAh battery and is currently $35. Even some of Anker's latest power banks and chargers that it debuted at CES have discounts as part of the Spring Sale as well.
