Best List: Apple iPhone/Watch Powerbank by Zens

When traveling, if you forget your charger, you’re often hosed. Especially for the Apple Watch. That’s why I keep a Zens Powerbank battery pack in my bag. The Powerbank features a built-in charger for the Apple Watch, plus a USB port for plugging an iPhone or iPad.

It’s light and easy to carry around, yet has enough juice for recharging an Apple Watch almost 12 times. Best yet, the Zens Powerbank battery pack is available now in Cult of Mac’s Watch Store. 

Zens' iPhone/Apple Watch Powerbank has a 4,000 mAh capacity, which is good for two full charges of an iPhone 7.

One battery, two devices

Designed by Zens, a Dutch company that specializes in wireless charging systems, the Powerbank is Apple MFi Certified and rated at 4,000 mAh.

That means it’s good for two full charges of an iPhone 7 (which has a 1,960 mAh battery); 1.5 charges of the bigger iPhone 7 Plus (2,900 mAh battery); and about a dozen full charges of the 42mm Series 2 Apple Watch (which has a 334 mAh battery and is currently the biggest battery in the Apple Watch line).

It had a standard USB 2 port for plugging in an iPhone or iPad and can charge both devices at once. The USB port outputs 2 amps.

The Apple iPhone/Watch Powerbank is a fantastic space-saving way to charge your Apple iPhone and/or Apple Watch.

The Powerbank is strudy and well-made. It’s measures just over 5-inches long, slipping easily into a jacket pocket or laptop bag. It can double as a desktop charging dock, and is ready to go if kept plugged in.

Overall, the Zens Apple Watch/iPhone Powerbank is a good two-in-one travel charger that’ll keep your devices topped up.
