I got this about a month ago and I love it! I used it once and it lasts such a long time!! It’s a bit pricey but it’s really worth the money if you plan on using it a decent amount, also it’s so sleek and thin, really easy to pack or even put in your pocket.

Possibly the BEST power bank that I've purchased. Not only could I charge two devices at once, the charge is faster than my original power bank. I could get almost four complete charges on my cellphone while I'm on the go. Definitely worth it at a decent price point that won't break the bank. It's stylish and compact. Highly recommended.

i love the textured fabric and fast charging capabilities! good capacity too! i like that it has a usb-C power in/out port, and two usb-A out ports.

Needed this for a trip, and it was very reliable for charging on the go. My smartphone charged as fast as any fast wall charger and it lasts a very long time. Fits well in pants/jacket pocket. Definitely recommend for the price and portability!

Recently purchased this battery charger explicitly for keeping my son's iPhone 13 powered throughout the 3 day Pokémon Go fest in NYC. Fully charged, and a 6 foot usb C to lightning cable, my son tossed this into his backpack and went to work. This battery charged his device about 6 times over and not once did he have to utilize a Powerbank in the park. This a great battery for traveling through airports, camping, or having on hand for when the power goes out. You can rest assured that you'll be able to charge multiple devices such as smartphones, tablets, and headphones.

With over 4 years of usage to-date, reliability remains above expectation, being utilized to allow extended photo & videography session as the main power supply for a Sony APS-C rig operating on a dummy-battery. USB LED lighting is used simultaneously with camera & accessories, all operating at 100% luminosity & cooler spectrum tones, for the duration of sessions. At any given days' end, the Anker powerbank has never been drained below the second indicator light, having concluded 4-7hr sessions of mixed 2160p @ 30 video, 1080p @ 120p in-camera slow-motion video, and 6k HDR imaging; this includes wireless transfer of files from camera to mobile device. The 'trickle-charge' feature is useful for supplying power to devices which have unclear voltage/amp specs and/or have susceptible power limits. [i.e.: low-end wireless earbuds, legacy pre-nanometer technology mobile devices, non-controller circuit LEDs, etc.]. Though not boasting end-user serviceability, if i can find more of these for reasonable prices, I would definitely still acquire several more for expanding upon an on-the-go workflow/gear-set. As I tend to favor the older designs of Anker's powerbanks that allow two-way usage of the USB-C PD ports (most are "input only"); this was far less common with pre-GaN & pre-readout designs when accompanied by 2 or more additional USB-Qi headers.

It works perfect for what I needed it for. It charged pretty fast and i just unhooked any cords when not in use just in case that would drain the power. But outside of that, i give it a 10/10. I have it in my pocket as we speak since i have a long day ahead of me. I've had it for over a month to give myself true time to test it out and it's definitely great for all day use and multiple device charging. It held well all day for at least 2 items. I haven't charged past 2 items at once to really push it yet.

After loosing my first Anker battery pack during a vacation, I didn’t think it twice and got the same exact one again. The way this battery pack works is amazing! It charges your phone up to 80% in 30 mins or less and with one charge you can charge your phone multiple times. Highly recommend it!

This product has supported me for several years now . I travel throughout the United States and I can say without question this product has kept me in touch with family, friends and work. It charges fairly quick for its capacity and has continued to charge all of my devices without loosing batery capacty over three years , and i rely on this product daily . I couldnt be more satisfied with this purchase .

The Anker Power Core III portable charger is a good product. When on the go you don't have to worry about your cell phone dying. However, it's called slim and it is not and I find it heavy just another bulky item in my purse. It's the same width and length as my Google Pixel 4a cell phone and it's heavier than my cell phone. It's also a bit pricey, I broke down and purchased it only because I couldn't get you know who to ship it to the Caribbean. On the next upgrade maybe you can focus on making it lighter weight and half the size.

Right out of the box, I only had about 30% of the charge left on the portable charger. For reference, my phone was at 20%. It charged my phone to 85 with about 20% battery still left. As some have mentioned, yes it is bulky. But you honestly can’t get better than this, its still slim enough for a jacket pocket, compact enough to fit in a bookbag and not take up an ounce of space.

Really nice powerbank, I love the small pouch it has and that it comes with one small USB-C to USB-C cable.

Lomg lasting, ease to use.sleek does what intended

Nice powerful power bank! I like Anker brand in general, I’ve never had a single issue with anything from them. This power bank looks cool and is a workhorse. I use it daily to charge my phone, watch, iPad, autel scanner (automotive) and I be used it to charge my Noco gbx55 jump pack. No complaints as usual with Anker stuff. Style wise, the only thing that would work better for me, is if the bottom of the power bank had like a rubberized coating, at least for me. How it is, makes it easy to slip in/out a pocket so I guess that works for most better. Nonetheless, solid product.

Works great, charges phone quickly as I was on my international trip sightseeing. Charges and recharges from same USB C port.

I never leave home without it ! It lasts 3-4 whole charges and it charges fast Im glad i bought! Its a life saver !!

Perfect power bank - easy to use, long lasting battery, great quality.

Large charge capacity and the fast charging feature is great!

Just got mine today, and it's charging. The fabric is a nice touch and it feels solid. I'm using a meter on the wire while it's charging and it will pull 18W charging as advertised, nice touch. Some other packs advertise crazy watts, but pull 1/3 to 1/4 what this one can actually charge with.
