Anker Portable Magnetic Charger and the iWALK Portable Apple Watch Charger

When you’re away from home and find your Apple Watch battery running low, having a portable charger can offer a quick power boost for it and other devices, too. While they feature a variety of capabilities, the best portable Apple Watch chargers will all have a compact design, device protection, and enough juice to power your watch multiple times. Some portable chargers can even charge your phone or tablet.

What to consider when choosing a portable charger

There are two main types of portable chargers: those that have a built-in power bank and those that plug into a laptop, car, or power outlet to provide a charge. Chargers with a built-in power bank may offer more versatility in terms of where you can use them, but they require periodic recharging and are typically a little larger in size. Also, keep battery capacity in mind when shopping. It takes approximately 300 milliamp hours (mAh) to fully charge an Apple Watch, so a 1,000 mAh power bank would charge your watch about three times before needing to be recharged. On the other hand, plug-in portable chargers are more compact than those with a power bank, but one potential downside is that you’ll need a separate power source to charge your watch.

Additionally, some portable chargers are MFi-certified and meet strict Apple standards for quality, compatibility, and safety. While there are many chargers with positive reviews that aren’t MFi-certified, choosing a charger with this certification means there will be less chance of damage to your Apple Watch via overheating, over-charging, and short circuits. Also, consider whether you’d like your charger to power more than just your watch. Some portable chargers can provide multi-product charging capabilities for your iPhone (requiring approximately 3,000 mAH for a full charge) and iPad (almost 9,000 mAh), but they may cost a bit more.

Lastly, consider the overall design that’s most convenient for you — some options can be hung from your keychain, unfolded to display the watch on your nightstand, or include LED lights to indicate how much battery they have left.

With these considerations in mind, check out the best portable Apple Watch chargers available on Amazon.

One reviewer wrote: “I love this charger. I carry it with me daily. I am able to charge my watch while I shower at the gym, drive, and at my desk. It's great to be able to charge while I wouldn't be active anyway, so I don't lose "move" calories. Super convenient that it doesn't need to be plugged in while it charges. I would totally recommend!”

One reviewer wrote: “Needed a portable adapter for my new Apple Watch SE and came across this little guy. Anker has been my go-to for most electronic accessories and once again, they hit the spot! I popped it in a power bank w/ PD charging (also by Anker. Big surprise!), threw my watch on it, and charged perfectly! [...] If you’re on the fence, I’d say go for it! Especially if you’re looking for a reliable MFi certified device.”

One reviewer wrote: “Ive gone through so many portable chargers and this one is by far the best one I’ve purchased! It works fantastic and it is so easy to just take it with you everywhere you go! The colors they have are great too! What I really love about this charger is that it charges both your iPhone and iWatch and they charge fast! [...] This product is definitely a game changer!”

It’s MFi-certified, has a nonslip rubber base, and uses a hardwired, 3-foot USB-A cord that you’ll need to plug in to charge your watch. While this charger doesn’t list the Series 7 as a compatible device, it does charge Series 1 through 6 (including SE) and comes with a convenient zippered travel pouch and a one-year warranty.

One reviewer wrote: “After forgetting my charger on a couple of camping trips, I purchased this so I wouldn't have to unplug (and sometimes forget) my home charger, when I go on trips. It's nice and compact and I love that the arm is adjustable to put the watch in nightstand mode. Charges at least as fast as the original one that came with my watch. When camping, I plug it into an external battery while I'm sleeping and am good to go for another day. I know I could go without it while camping but I like having the activity monitor and am just used to seeing my watch on my wrist. I can also keep this in the car for a recharge while driving, just plugs into the car charger.”

One reviewer wrote: “I don't know what I would do without this little charger. I have the Apple Watch charging cord by my bed, but I almost never use it because I wear the watch when I sleep. With this charger, I charge my watch in my car on my commute to work, at my desk when I'm sitting, and if I'm out and about. I charge the charger at night while I'm sleeping and then have it with me all day. I don't have to find a place to plug in a cord, and it will charge my watch more than once per day if I have had a big battery drain. I love it!”
