    • Compact, powerful, and perfect for keeping my headphones charged at the gym
Color: Black
We’re always finding ourselves with dead headphones right when we want to work out, and the Anker Nano 10,000mAh 45W portable charger completely solved that problem. A single full charge from this power bank can recharge my AirPods Pro over 10 times, and it can get them from 0% to enough battery for a full hour-plus workout in just a few minutes thanks to its Power Delivery (PD) fast-charging support. I was cautious at first because I’ve seen other portable chargers recalled for fire risks, but this one is recall-free and feels very safe to use. The 10,000mAh capacity gives plenty of stored energy to charge multiple devices multiple times, and the 45W output via USB-C means it can even handle tablets or small laptops in a pinch. The USB-A port also supports standard charging for older devices. It’s very compact and lightweight, making it easy to keep in a gym bag without adding bulk, yet it still delivers serious power. I’ve used it for AirPods, my phone, and even a tablet during travel, and it works flawlessly every time. Overall, this charger hits the sweet spot of portability, speed, safety, and capacity, and it’s exactly what I needed to stop worrying about dead devices mid-workout. ... show more

    • Portable and big capacity
Color: White
I’m currently using the Arc Pulse case on my iPhone 17 Pro Max, so that basically eliminates all magnetic/MagSafe chargers. Therefore, I wanted a portable battery pack that was a decent size and weight but also had at least 10kmAh in case I needed to share this with my wife in one day when traveling. When I saw this charger, I thought it’d be perfect since it has a built-in wire with more than enough slack. It’s also a bit smaller width- and length-wise when compared to batteries of the same capacity, although, it’s slightly thicker. I prefer charging with a wire since, when using a charging block with the proper speeds, it’s usually faster than wireless charging. The available USB-C port can serve as an extra port if you need to charge two devices at a time, but it can also serve as the input when needing to charge this battery pack (the same goes for the built-in wire). There’s also a USB-A port but who really uses that still? I love the little display also. It shows the percentage left for this battery pack, and if you’re charging it, the display will show the time left to get to 100%. You can also charge your phone while charging the battery pack, but honestly, it might be better to just charge each item separately since I think doing this just makes the power “pass through” the battery pack and into your phone. I don’t think it’ll charge both simultaneously. Overall, great and compact battery pack while not needing to carry an extra wire. It can easily be placed in any bag or sling, and with the built-in wire, you can even still use your phone without needing to have a heavy magnetic battery pack attached. ... show more

    • Excellent Travel Charger
Color: Black
This charger is well designed. I have been in the wireless industry for decades and it is not often that you see products this well thought out. I love the precise meter that shows you the exact state of the battery. Because of the size, it isn't likely that you will get more than 1 to 1.5 charges out of it, but that's perfect to get you through the day. My wife used this on a trip to Europe and was able to stay connected all day thanks to this lightweight, compact charger that fit nicely into her travel purse. It's a good value at regular price, but if you can catch it on sale like I did...even better. After seeing how well it worked, I ordered a second one. ... show more

    • Perfect Travel Power Bank
Color: Black
This power bank is compact yet very powerful. The 10,000mAh capacity and 45W output are more than enough to keep my phone and other devices charged while traveling. I love the built-in retractable cable—it’s super convenient and means one less cord to carry. It feels well made, charges quickly, and is the perfect size for a bag or carry-on. Highly recommend for anyone who travels often or wants reliable power on the go. ... show more

    • Smaller, chunkier than expected.
Color: Black
Small (smaller than expected,) compact, hefty battery brick. Fits into any carrier ( mine is for my suitcase). Easily held in one hand. Seems to charge well.

    • Best power bank I’ve owned yet.
Color: Green
Review Image by Bates Reviews Bates Reviews
Super sleek and easy to use. I carry it on me at all times. The best part is the built in extendable power C cable. Nothing extra or messy to carry. It is super fast at charging and lets you know how much power remains. I’ve started switching over to Anker for all my power needs.

    • Super portable
Color: Black
Super portable. Good quality. Quick charging. Retractable usb-c cable. I added one more usb-c cable (short one) so I can charge two devices at once. Very easy to carry in my daily backpack (not too heavy, just right)
