As part of today’s Gold Box Deal, Amazon is offering the Jackery Thunder X 20100mAh Portable Battery Charger for just $29.99, a discount of 67 percent.
With a whopping 20100mAh battery, the Jackery Thunder X can charge your iPhone 7 up to eight times according to the company. If you happen to have a device with Quick Charging, this battery can also provide up to 80 percent of your mobile device’s battery life in less than 35 minutes. This external battery also comes with an 18-month warranty in case anything goes wrong.
All-in-all, this is a great deal for anyone looking for an external battery. I’ve used some of Jackery’s products, and I have to say they’re still working without any issues. In fact, I think the Jackery Bolt is the best portable battery charger for most people.
