It's a Good Idea But...

8/18/2019 by Anna

The size is great and the idea of producing an energy bank for both the watch and a device is awesome. Unfortunately, when I put my second generation Apple watch on it it didn't charge and a message came up on the watch saying it wasn't a "compatible" device. In terms of charging my phone, a full charge on the bank took my iPhone X up to about 75% battery power. This was plenty to get me through the day but I wouldn't count on it for a full charge. On a separate occasion my iPad was almost dead and the bank took it up to about 30%. So it's handy, but watch your expectations.More > < Less

Great potable charger that holds charge longer than any other portable charger. Is great for traveling. Does not work on Fitbit watches.


Great for travel!

Love that this charges both the Apple Watch and iPhone. I have already used on 2 trips. The cable (mini USB) to charge the Time Traveler is a bit hidden in the packaging. Also, would be nice if it had a case or bag included.More > < Less


Not what it claimed

I purchased two of these chargers, one for me and one for a friend because neither of seem to be able to keep our watch charged. Its claim of how many charges you can get off of it before recharging is not even close. Does not pack the punch i had hoped for.More > < Less


Careful how you use it

I thought by keeping the charging device plugged into power overnight that I could charge my Apple Watch, iPhone and iPad at the same time. What I found is that is that the Watch would recharge, but the other devices wouldn’t necessarily receive power. That said, it does work well as a power bank, offering a supplemental boost (if not full recharge) to the phone or watch as needed.

From the Maker:

"The Time Traveler has a maximum power output of 2.1 amps. A fully drained iPad typically requests about 2 amps to fully recharge, while an iPod requests about 1 amp and the Apple Watch requests about ½ amp. Trying to recharge three drained devices at one time may result in sub-optimal results. Try charging one device to full power and then plug in your other two devices. This should provide enough power to recharge your remaining devices."

About Time Traveler

Portable Charger

Time Traveler is an Apple Watch portable charger that can power up your other favorite devices, too, when you’re away from home.

The pocket-sized battery bank can charge three devices at once by combining an induction charging pad, a built-in Lightning cable, and a USB port. It’s an all-in-one, on-the-go solution that’s perfect for travel.

When charged up, Time Traveler can provide around seven Apple Watch charges, or give other devices an emergency boost. And it’s the only Apple Watch charging solution that supports Nightstand Mode—which is when the watch functions (on your nightstand) as an alarm clock.
