Great for daily carry, for topping off several times a day, if you're not a Power hog!
With 6,000 mAh, I find this is just the right amount of power to carry around for daily use. I can power my iPhone nearly 3 times during the day, which is more than enough for most of my days. If I anticipate needing more power, I'll reach for my 8,000 or 10,000 mAh charger before running out of the house.
While this battery is a bit larger than some, it's cheap, and will fully charge my phone 1.5 times from dead. It is always important to compare a charger like this to the battery in your phone to ensure there is a large enough charge for your phone.
I’ll start with the positives first - this battery provides a lot of extra power in a relatively compact form.
Now for the negatives - the build quality isn’t all that great. One of the two USB ports on this stopped working within a month of me buying it (and only after 1 use). Fortunately, it has two USB ports so I just have to make sure that after I plug in, my device is actually charging.
This bank takes hours to charge, probably about 10h. Also the "double-click" to engage the light is very annoying if you turn it on by accident and then don't remember that this is the way to turn it off! I feel like sometimes it discharges more quickly than others but that is a little hard to gage given that a phone can act weird at times too in terms of drawing power.
I purchased two of these as gifts to my daughters so they would have power if their phone runs out.. One daughter has used it numerous times in the few weeks she had it and it has worked very well. Just like others it takes a long time to recharge but overnight is plenty of time. I would recommend it.
