Cobalt: Charges from portable fans to phones very quickly. The power charges quickly as well and holds the charge for a long time. Modern style but does weigh a bit but I use at home we have lighter ones for purse and pockets. Brand Mophie Connector Type Micro USB Battery Capacity 800 Item Dimensions LxWxH 6.77 x 3.35 x 0.88 inches

This mobile battery is awesome and saved me during a recent video shoot for work. My phone got down to 10% battery and this item charged it back up to 60% within 5 to 10 minutes. The battery seems to hold its charge for a long time. It’s also easy to travel with. I am very happy with my purchase.

It charges my phone to 100% at least 6 times before it needs a charge itself. A smidge bulky and has some weight to it. But well worth it to have a guaranteed charge.

Got it and so far it works great Wish they had put something on so you could hook it to things

I love this, never have a dead battery again. Charges fast and is convenient. I highly recommended for every household.

Works perfect for on the Go ! Durability charges my phone for hoursand it's portable

Great size and charging capacity

Love it. Bought cause my daughter keeps taking my other powerful charging bank. Takes a while to charge the first time.

a little big for my pocket but great battery power great power

These work well and really do charge up my iPhone quickly.
