The Kingrow K1 E-Ink Smartphone has no blue light, which helps keep your eyes healthy. You might be used to straining your eyes when looking at your smartphone for—let's be honest—hours. It's easy to get lost in the scroll. With this e-ink smartphone, however, you'll be able to scroll as long as you want without sacrificing your eyesight. If you switch to this smartphone with no blue light, you'll still get all the capabilities your current phone has. In fact, it even has two SIM ports so you can combine your personal and business cellphones into one device. And this anti-glare smartphone ensures you can clearly see the screen for as long as you want. Its standby time is up to 400 hours, so you may only need to recharge this e-ink phone a couple times per month.
