Zens Power Bank is a great little Apple Watch battery [Review]

Most external batteries for the Apple Watch are BYOC -- Bring Your Own Cable -- and have bulky winding systems for tucking the cable away.

Not the compact Apple Watch Powerbank from Zens, perhaps the most portable external battery pack on the market.

Hip to be square

Zens Apple Watch Powerbank is one of the only chargers with its own built-in magnetic power adapter. So no more tangle-prone charging cable.

Made by a Dutch startup called Zens, the Power Bank is small and portable. Available in either grey or white, it measures just over an inch cubed. It's too bulky for skinny jeans, but is easily tucked into a bag or jacket pocket. It's certainly the smallest, lightest battery pack we've come across.

Charge!

Charging is activated by a small button on the side. Four LEDs display the available juice. The Power Bank itself is charged via a microUSB port on the other side.

The Apple Watch charges when laid across the top, but the Power Bank works best if the watch band is closed around it. This keeps the watch firmly on the charger and allows it to be laid on its side for Nightstand mode.

The Power Bank features a 1,300 mAh battery, which Zens claims is good for up to three full charges. It's only 500 mAh short of the Nomad Pod Pro, which is rated at 1,800 mAh and is much bulkier.

In testing, we got two-and-a-half charges using a 38mm Apple Watch, and two full charges with a 42mm Apple Watch, which has a slightly bigger battery. That's plenty for short trips or a long weekend. I took it on a four--day camping trip and it kept my Apple Watch alive the whole time I was away.

Compact and convenient

The Powerbank offers passthrough charging, so it can be a full-time charging station. I have it on my desk at work. I charge my Apple Watch during the day, and it's always charged up and ready for a trip.

The Powerbank is assembled from Apple-certified parts, so it's not cheap. It costs an eyebrow-raising $49.99, which is kinda pricey for such a small accessory. However, it's well-made and unlikely to burst into flames on your bedside table or a transatlantic flight. You're paying for quality.

The Zens Powerbank is the most versatile and handy charger for the Apple Watch I've used. It's the best travel charger I've come across so far.

Price: $49.99 with free shipping!

Fantastic Watchband!

Had my eye on this watchband for a while, and finally found someone who had it in stock! Excellent fit, though a little snug (I have large wrists). Excellent quality! If you're interested in a Twist-O-Flex for your Apple Watch, definitely check it out. Only thing that would make it better is if I could add like three links to it, but again, this would be for my personal preference.

It’s beautiful

👍

Really nice case for my iPhone 12

This case looks and feels great -- and it fits the phone perfectly! It seems to give really good protection to the edges and corners. As another reviewer noted, the bottom is left open for the speakers and charging port....I don't see this as an issue, but your milage may vary.

I usually just carry my ID in the back pouch, but I think I could get a couple of credit cards in there, too. Overall, this is a pretty darned nice case for my phone.

Nice!

This is a birthday gift for my daughter who has an Apple Watch. I haven't given it to her yet since it's 4 months away (and I don't own one so I can't attest to how it fits) but it's really well made and looks terrific. She's an Apple-holic like me so I know she'll love it.

Looks like real MOP

The case is pretty, light weight and semi-flexible and has the visual depth, shine and appearance of real, black MOP. What you see in the picture is what you get in real life. It’s good looking, sophisticated and perfectly compliments my black iPhone 12 mini. I also like that it is a one piece design and that the edges of the case are slightly elevated around the face and camera openings so that you get a tiny bit of bumper protection (without the bulk of an actual secondary outer rim bumper) in case you drop it. I also like that it has a shiny finish so that, while it’s not “slippery,” it still slips in and out of my purse or pocket easily enough without dragging against any of my stuff that has a cotton lining, like some of the rubber or silicone cases tend to do. I don’t feel like I have to fight with it to get it into or out of a small space. Overall good looking, functional phone case. I like it!
