    Last fall I had the chance to take a look at ZENS' all-new Dual + Watch Wireless Charger, which offers spots to charge two Qi-enabled smartphones and one perch for the Apple Watch. I came away quite liking the accessory, which should be a great charging hub for anyone in a two-person household, and now the company has launched a companion accessory called the ZENS Dual Wireless Powerbank.


    This device is a portable battery pack that itself includes two spots for wirelessly charging an iPhone 8 or later (or any Qi smartphone), similar to the design of the Dual + Watch stand. The Powerbank has a 9,000 mAh battery, two USB-A ports, and one USB-C charging port on the rear (USB-C to Lightning fast charging is not supported). The device itself also supports wireless charging, so you can place it on the Dual + Watch stand without needing to mess with wires to fuel up the Powerbank more easily.


    ZENS mirrored the design of the Dual + Watch Stand for its new Powerbank, and both accessories have a nice rubberized texture on the mat where you place your iPhone. Instead of aluminum on the sides like the stand, the Powerbank has a plastic enclosure that still has a nice heft to it.


    Just like the stand, I really like the simple design of the Powerbank. Black isn't usually a color I opt to use in stands as big as the ZENS Dual + Watch, but I've been using it since I reviewed it last October, and the only downside I've come across in the past few months is that it is definitely a dust and fingerprint magnet.

    I’ve been looking for a decent new battery bank with Qi charging on amazon. There are a ton that have an insane amount of fake reviews. I’d like something with at least a 9,000 mah battery (20k would be great), and quick charge ability. Solar would be a bonus (I have 2 older banks with solar that are nice for keeping it somewhat charged when not in use). Will keep an eye out for this one.

    Interesting product. I wonder what the life expectancy of the batteries are with the heat generated by the wireless charging?

    I understand that the convenience factor makes wireless charging appealing for a stationary situation with a pad or stand situated on a nightstand or desk where it's easy to grab and go.

    But a portable powerbank?

    Powerbanks already sacrifice at least 20% of the battery's energy due to conversion losses (and that's on the better end).

    Then add another 20% (again, on the good end) for the inductive charging part.

    Not sure what the appeal is there.
