We introduced Anker’s Astro 3 large-capacity power bank last week, but if you need a more portable option, their Astro Slim3 backup battery may be more suitable for you.
The Astro Slim3 is an ultra portable, mid-capacity backup battery that measures 5.3 x 2.7 x 0.47 inches and weights 3.9 oz. As we can see from the images, the power bank features smooth, compact design, and comes with a built-in 6000mAh backup battery that is undoubtedly able to offer enough power to your smartphone or tablet on the go, and its integrated micro USB cord lets you conveniently charge your Android devices, while its USB port is ready to charge your iOS and other mobile devices. Apart from that, the LED indicator shows you the status of the backup battery.
The Astro Slim3 backup battery is priced at $32.99 USD. If you’re interested, jump to Anker official site for more details. Additionally, if you need other options you might like to check the dual device backup battery and more via “backup battery” tag.
