    My other Anker battery started bulging— I forgot it in my car :/ So I bought this one to replace it. Fast charging and I really love that it comes with its own cable, which also works as a handle to carry it—convenient!

    Best portable power bank ive used so far. I use this to charge my MacBook most of the time. And once in a month i use this to charge my other low powered devices such as jlab epic keyboard and mouse. Amazed by this product’s efficiency in charging low powered devices. Inbuilt c to c cable is a win for me.

    I am using this portable charger and it has been an absolute blessing. I can charge my phone up to three times fully. The charge on the power bank does not leak so I can charge it now and then use it after two weeks and I can still charge my phone. It’s a great product. Really reliable product, and affordable.

    Anker 20,000 mAH is great! Long life , fast charge with digital battery life display. Solid battery and heavy, which I like because that usually means tough. Also has a charging cord attached to the lanyard, no more hunting down charging cables.
