    I was taking a trip to Washington DC and knew I would be taking a ton of pictures. This was great for charging on the go. It wasn't super bulky and charged fast. I definitely would recommend!

    No Travel pouch - Best charger

    This is our 3rd Anker charger. It works fantastic. The reason why 3 stars it didn't come with the travel pouch as it states on the packaging as well as on the Best Buy website. I like having the pouch to store the charging cable and charger all in one place.

    Easy to use and holds a good long charge. Traveled for 4 days and used charger on the plane and in car driving to different locations. Did not have to recharge until I returned home.

    This feels sturdy and it works well. It doesn’t seem to charge my phone for a very long period of time, as I shave to charge it more frequently than other brands. Unfortunately, when I went into the store I asked the sales person to get me a charger with a power cord so that I could charge my phone from battery storage. She assured me that this product came with a cord. Well of course it doesn’t, so I had to go back the next day and purchase an additional cord. The sales people should know what they’re selling and not make false promises.

    Very slim and lightweight. When fully charged, it holds for a long time (I've fully charged my phone when it was less than 20% three times). I was also able to get into a concert with it, no problem. On the more expensive side, though.

    10k is not the best. It is only 2 charges of a phone, but it is a quick fix for travel. It is not fast charging.

    This Power Bank works very well as long as you keep it charged and it charges two devices at the same time for at least 6+hrs

    Have used it for few days only, overall the battery seems to be good built with quality, it's light weight too. One thing to note is that in general, all batteries are more expensive now.

    Bought this for work to be able to keep my phone charged all day. I can charge this up from 0 to 100% in about 1.5 hrs and charges my phone up even faster.

    This charger held its charge for a very long time. I took it on a trip for three weeks and it still had a good charge when I got home. I would certainly recommend it.

    Have not fully worked this to see if it will perform as advertised on the packaging but charge time on the device was not bad and the ability to charge two phones (if needed) is a great option. Hoping this will last and perform well for a number of years.

    Gets the job done, don't like that the type C is input only doesn't charge. Construction feels on the cheaper side but all in all it's only a battery. Does exactly what it advertises.

    I waited a week after purchase before reviewing so I could at least give a decent review on the product. I bought this for my daughter who's heading to her first year in high school this year and she uses her phone and a tablet throughout the day for school work and between classes to communicate with friends. She used to have to limit her phone usage to keep her battery working all day, not anymore. She said she has recharged her phone twice so far on this battery pack with one tablet recharge in one day and it lasted that day. She plugs it in at night when she gets home and it's charged in the morning when she puts it in a pocket in her backpack to use throughout the day.
