Portable Charger Power Bank 24000mAh 4 Output Ports Huge Capacity Battery Pack with AC Power Adapter for iPhone, iPad, Samsung Galaxy, Android and Other Smart Devices

I absolutely love this portable power bank!! if 100% at the beginning of the day, its still about 40% by the time i go to bed! my samsung phone has the WORST battery life, and this brick keeps it alive all day long! unfortunately yes, its a brick-like power bank and can be inconvenient to carry around, but if youre a student and can keep it in a backpack or bag of some sort its very handy. I can also charge another device at the same time and still have charge in the power bank by the end of the day.

I love the style of the power bank, and the digital battery meter. however after it reaches 50% life it basically dies. I get maybe 2 charges on my 7 plus.

Was not 24000 mAh. Seller never responded to question either. This pack charged my phone from 20-50 and the battery pack displayed 59% from 100%. My phone has a 2700 mAh. It charged 810 mAh worth but the battery pack displayed that it took 9840 mah based upon percentage. That's enough to charge my phone over 3.5 times. At that rate I could charge my phone maybe 1.5 time before the battery pack needs to be charged another 8-9 hrs. I can't even find the brand online anywhere so it's obviously a cheap battery pack. Stick with the known brands. Avoid this cheap product that more than likely makes %400 profit on one sale.

Bought this for deployment, and it's an absolute badass. A year later, I still use this for charging my phone when I'm low on battery at work (I have bad service in my building and it drains the battery fast). Charges my phone pretty quick, several times over. Protip: this power bank will charge pretty quick if you use the white Samsung "lightning charger." The included charger that comes with it is pretty sluggish.

It a solid power bank and shows the percentage correctly, also it has 4 ports on it. It does come with a adapter and cable to charge it. It also has a little piece of plastic on the percentage screen, so when you open the box and see that there are marks on the percentage area its just the plastic. I saw it and freaked out until i saw the plastic cover. It also comes with instructions.

This is a heavy, robust unit! You are able to use a fast charger to charge it, but I would recommend using a lower amp charger to make this last longer. I'm just that way with my electronics. Performs as it describes. No issues experienced with charging several devices at once. Unit still has over 90% charge on standby after 2 weeks!!! Flashlight could be better, but nice feature for quick peak in dark, if needed.

Somewhat thick and heavy, but will charge my iPhone (when it's below 20%) 4-5 times before needing to be recharged itself. Recharges quickly.Update: after 6 months of moderate use the micro USB charging port loosened and no longer works. The unit also charges via a lightening port (nice to have both types of charging options), so it is still functional

The charge indicator is already inaccurate after a few uses. It took over 18 hours on one recharge for it to finally indicate fully charged. I only got about 2.5 recharges (equivalent to about 1.75 full charges 0-100) of a smart phone out of that before it was completely dead again.
