I have this in white. Works as a pass through so I don't need to carry the cable. Works good so far.

No it is a power bank and will charge on its own, the percentage indicator shows how much battery life the power bank has left.

Community Reviews

This JOYROOM magnetic Apple Watch charger stands out as a compact travel and backup power bank that can charge the watch while its own battery is being recharged. It is handy in a work bag or car, lightweight enough to carry often, and the built in cable and magnetic dock make it easy to use on the go. Reported battery life ranges from about two to three watch charges, with some also using it for AirPods or an iPhone in a pinch. The main drawbacks are slow charging, a 3W output that does not deliver true fast charging, and a battery indicator that can read inaccurately or keep draining after the watch reaches 100 percent.

Common Questions (5)

  • Yes. It can charge your Apple Watch while the power bank itself is being recharged, and the built-in cable can be used to recharge the battery from a USB brick. That makes it useful as a desk, car, or travel charger without carrying extra cables.

  • It charges, but it is not fast-charging: the output is reported as 3W, and a Series 10 took about 30 minutes to go from 52% to 81% and around an hour from 50% to 100%. It is fine for emergency or portable use, but not for Apple Watch fast-charge speeds.

    nutsaboutgolfnutsaboutgolfnutsaboutgolfDanielW3719

  • The percentage display can be inaccurate or stuck at 100% or 0%, even while the charger still works. Some units also keep draining after the watch reaches 100%, so it may be best to remove the watch when charging is done.

  • Yes. It is described as lightweight, small enough to carry, and handy for trips, work bags, backpacks, and even the car. It has also been used successfully on travel, including an Australia trip.

    sjjonespreferredmikepublicltvns1

  • It can typically recharge an Apple Watch about 2-3 times, including an Apple Watch Ultra 2 or Apple Watch 6 in reported use. The exact number depends on the watch model and battery size, and the stated 2500mAh capacity may not translate to a full 2500mAh of usable watch charging.

I have one of these and while it does work, it has some kind of design flaw. The battery continues to drain down to 0% even after the watch is fully charged. You have to remove the watch once it's done.

Can someone explain to me what you guys mean by passthrough charger? Like it can be plugged in and if it's a 0% it can charge the watch? I assume that's what you guys mean. Can someone confirm
I think passthrough charging in this instance means that the device can charge your watch at the same time the battery in it is being charged up itself.

That's interesting, so it doesn't auto stop or turn off when watch is at 100%. That's like a major flaw. What if you want to charge watch overnight then the portable battery is dead then by morning or not fully charged.

It's says it's fast charging, which should mean it's 5w. But can anyone confirm?
Just got it, says 3w

Thanks. I already ordered one and received it, so I'll try it out.

Of all the IP that Apple enforces, I wish they would crack down hard on "fast charging" for Apple Watch. It's near impossible to tell if you're gonna get actual fast charging or not.

Just got it, you can charge the watch while charging the device. My display works...In 5 minutes, while the S10 46mm was charging, the device went from 76% to 78%. The device's max charging speed for the watch is 3w

I wonder for traveling if I would be better off with something like this if it was $10 https://www.amazon.com/Retractabl...LDZB8&th=1

That deal comes and goes, so either see if someone posts it again next time it is working, or just Save for Later, then toss back in your cart from time to time to see if it's working again.

Charges 50% for my iPhone 16 Pro and upto 3 times for my Ultra 2. Small enough to carry around.
