This is the second Gogyre Portable charger I’ve owned and I have to say they make some durable products. It’s not the slimmest in side but it makes up for that by being compact in both length and width. There is a tiny row of blue lights on the top right hand corner that is the power indicator to let you know how much charge it has and how much power is left when you are depleting the power. It’s black with silver trim and pretty light weight so it’s convenient to carry around.
The capacity is 5300mAh and for my phone it will charge it once fully and nearly one more additional time. It only charges one device at once but the output is 2A so it will charge you devices very quickly. The power cord that it comes with is also very short so there power doesn’t have to travel very far from one device to another but I have also used this with my other usb cords and it works just fine with any of them in case you loose the original one. As technology advances they are making these portable chargers with more and more capacity so as of right now this one ranks in the middle. It’s not the largest capacity but certainly not the smallest like those tube sized chargers that don’t hold much power. I received this item at no cost in exchange for my honest and unbiased opinion.
