I have a Samsung Galaxy S9+ and I believe this was able to re-charge my phone four times before needing to re-charge the Anker. It is easy to use and carry, although a bit heavy but not too noticeable in a backpack. Only downside for me was that you cannot charge C-to-C, which is the cable I had on me at one point - it has to be USB-to-C. The C-plug on the Anker is for charging the Anker, not the phone.

Anker is my go-to for power banks. This one here has a nice capacity and is pretty stylish. Nice slim design makes it easy to carry.

I took one of these batteries on a 2,200 mile hike of the Appalachian Trail with 2 Samsung Galaxy S5s and a 5th Generation 32gb Touch iPod and it lasted 10 days taking tons of pictures and videos, uploading them and listening to music, audio books and podcasts along with watching television shows and movies. Its rugged and durable and capable of charging multiple devices simultaneously. That's why i bought this battery again and can highly recommend it.

We leave this in the car in case we need a charger why we are in the field. Kind of heavy to carry it in a purse or pocket. Charge time is pretty long something like six hours. This charger will charge a large phone like a iPhone 14 max and still have capacity left over the bill. Quality is excellent. I would recommend it since I like Anker products.

Great, sleek, and lightweight portable charger. Works fast and is very reliable. Easy to use.

I bought this portable charger as a backup for my other one. It works great, holds a good charge, and charged my iPhone and iPad rather quickly with still a bit of power left afterwards. The price was decent (on-sale) and worth the purchase. I love that it is 20,000 mAh as my other is only 10,000. I would recommend this buy to others if you are searching for something that will be ready when you need a bit of power boost for your electronics. Happy shopping. :)

Bought this when there was a threat of a hurricane coming in to our area. It went to our East and we were spared. This thing charges up in a couple of hours and recharged both of our phones twice before it needed recharging!! Very sleek, a little heavy but it needs to be to be able to hold that much juice for your phones. I would highly recommend this battery charger for your cell phone or tablet.

Portable charger great for on the road quick charge for both laptops and cell phones. Charges quickly and lasts for hours. I also use whenever I read in bed with a chargeable nightlight. Perfect fit in laptop case or any backpack due to its slender build. This item has save me many-a-times whenever my cell needed charging while on the road. Priced just right! Multiple ports!

Bought this to take on vacation and it worked great ! Charged my phone many times on one charge (4-5 times). When my phone would go down to about 30% I would plug it in while it was in my purse and in about an hour I was at 100%. It did the job. About the size of my iPhone 8plus and about triple the weight. Was worth the price !

This has been a great purchase! It’s great to have with you when you aren’t going to be around a power outlet for awhile and need to charge your phone or laptop or whatever device you carry on the go. I was impressed with the style of the design and the quality of the product too. Definitely worth considering if you need something to power your devices on the go!

Well built and a very good price to mah. At least 3.5 full charges on my S21 Ultra. Pros: Large capacity Fits in a pocket/purse Fast recharge after depleted. Micro USB and Type-C inputs. Cons: Very heavy. Not a fast charge for devices. Only has USB-A output connections. I would recommend this power bank to anyone that travels a lot or just needs plenty of extra power on the go. The form factor makes it easy to take with you, but the weight could be a deterrent to carrying it in a pants pocket.

Works really, really well - So impressed! My car charger never works but this is perfect to take when on the road. It charges multiple devices, including an iPad (which never charged in the past directly with a car charger) and amazing to be able to take into a restaurant and charge. Highly recommend!

This charger packs a lot of power. I charged my iPhone 8 from (essentially) zero to 100% four times on one full charge of the Anker Metro 20000. Seems very compatible with phones and tablets. Had a bit of an issue with wireless earbuds, but I would seldom it for that. Seemed to fill the earbuds, but not clear full, as they would still register a red light, not the green light of 100%. Solid, has a carry case. Is a bit heavy, but nothing I worry about, even in a backpack in the mountains.

Fantastic! I originally bought a Best Buy brand Insignia 5,000mah portable charger as its intended use was just to keep a small electronic device charged throughout the day if the battery ran low. I would get one full charge out of it and it would completely kill the charger, even though it should have lasted at least 2 charges. I returned it and got this one. The difference is night and day. Yes, this is 20,000mah vs 5,000mah, so you'd think I would get 4x the charges and that's it. No. I fully charged it before use and I have only partially charged it once more. I have had this for almost 5 months now. This thing lasts forever compared to the Insgnia branded one. Plus the look is much cooler and the fabric on the front is awesome quality. If feels like a much better product. Good weight to it. Solid construction. I have had no issues. A full charge takes quite a while. My laptop is USB-C powered, so I use that charger to get the most efficient time when charging this. I couldn't be happier with the purchase!

I purchased this to use on my recent 5 day backpacking trip on a portion of the Colorado Trail. I was able to charge my cell phone and others in my group. I put a full charge 4+ times and there was still charge left in the device at the end of the hike! A little heavy but worth its weight! I would recommend. Easy to use.

I bought this charger to help with my and my sons phone on the slopes. We love to listen to music while skiing. Not only is it fast but the thing never dies. We went for a whole weekend only charging from the maker 20,000 and didn’t have to charge the bank until we got home. Small enough to fit in you pocket and powerful enough for two phones and a set of pods. Thank you

This power bank charges multiple devices in one charge. We travel and love these while waiting at airports or on long car rides. We can charge multiple devices at once. We have it for several years and its still working great!

Nice looking and not slippery in your hand. It won’t show marks either with the fabric like cover. It doesn’t seem to charge itself fast even with usb-c but holds a lot. Good quality well manufactured. Limited use for me so far but maybe five charges for an iPhone pro

Haven't used it so far, but I am hoping to be use it soon. It seems like it will last a long time. But, it is heavier than I was expecting it to be. I think I will still get more use out of my smaller battery. Yet, this will be useful for long trips.

Absolutely love this charger! I'm often all day with no electricity when working on film sets. It charges just as quickly as if it was plugged in. I even went to a concert and shared it with my boyfriend. We were both able to fully charge our phones and after that several lights were still on meaning we could have charged more. When you charge it, you will see the little lights flashing so charge it the night before and in the morning all the lights will be solid (not blinking anymore). Make sure ANY charger you get has at least 20000MAH. A lot of the ones advertised at Big5 and others will show 8MAH for $10. Only get 20000 and higher MAH and it will keep charging for you until you get home. Best purchase ever!! Love the nice black netting carrying case too.
