Question: how do I charge my cell?
Document: It Does not hold as charge for very long. It Takes forever to charge my cell phone. I should have sent it back
Often times I reach for my cell phone to find the battery dead. I have found myself in a bind more than once. Now I carry the Jackery Mini in my purse and instantly able to charge and use my phone. This is also great for tablet charging. With the mini,you never have to worry whether that airplane seat has a charging station.
I bought this little device because promised 2 full charges of my cell phone (I was especting at least 1 full charge), however its only able (with a full charge) to charge my phone from 13% - to 94% and then it dies. Not even a single full charge. It's a scam. I want my money back! :(
My work-supplied cell phone burns through a battery charge in unpredictable ways, and I have routinely found myself without a charge with no access to power outlets. I purchased one of these portable chargers, and have been carrying it for about a month. It is very lightweight, and carries enough stored power to charge my work phone almost fully. It has more than enough charge for my personal cell, as well as my Kindle.
I purchased The Jackery Mini Ultra Compact Portable unit one month ago. It appeared to have worked the first couple of times and has not been able to fully charge my Samsung Galaxy S3 since. I say "appeared" as I used it while travelling the first couple of times and can't recall exactly how much battery life was in my cell and how much remained in the Jackery before recharging it.
I had to travel for work, and based off consumer reviews thought this would be perfect. NOT the case, the charger charged while at home, worked the first time I used it, then after re-charging and having to use it to charge my phone again using the cord provided with the Jackery - the device over heated, stopped charging and left me with a dead cell phone battery. I will be returning it as soon as I get back from my tripl.
Works excellent so far; Went to an amusement park and drained my cell battery thanks to GPS and checking line wait times. By 3pm, my phone was dead. I plugged this in and within an hr I was able to use my phone effectively for the rest of the day. Some Notes: 1- This get HOT, so do not charge up your cell and use this in your pocket - plug in your cell/tablet and place somewhere else, like your backpack or car seat.
First full charge I purposely left if for a week before using. I wanted to see if it would keep the charge since I know it would be carried around for a few days before being used to charge a low battery. All led's lit up after sitting for a full week. My cell phone was at 17% and took approx 45-50 min to charge near 90%, an additional 30 min did not charge to 100%. The Jackery now has two led's.
I bought this product just before our recent trip to Walt Disney World where I knew we would be taking tons of battery-draining pictures and video. This little power source was just what I needed and it worked great! I was able to get about a full charge and a half for my cell phone with each use and it's compact size allowed me to carry it in my pocket without really noticing it's presence. It's been great resource and proved to be very reliable. I highly recommend this product.
My wife cell phone was on its last leg and she used this to keep her phone working during a last minute business trip.She would charge her phone and the charger at night and would be able to make it through the day.
Answer: Once your jackery is charged, plug your phone into it and push the grey button. I can get more than one full charge for my iphone 5.
