Portable Charger Ekrist 25800mAh, High Capacity Ultra Slim Power Bank with 2 USB Ports & Colorful Indicator,Power Delivery External Cell Phone Battery Pack for Smart Phone, Samsung Android, Table etc

Worked fine for charging both Samsung J7 and iPhone 7at the same time. Got 3 dual charges out of it. Downside is the weight. Got this for a hiking trip overseas so it was an ok trade off to make sure we keep our phones charged for the 3 day excursion. It did get flagged once in the airport xray but after the TSA agent checked out the bag it was in there was no problems.

It's a tad bit heavy and big (slightly bigger than iPhone 7) for travel in comparison to the other portable chargers I've used. Not clearly seeing the big difference in charging speed nor power to warrant the price, weight, and size. Can charge/connect two at a time so that's nice...

Well first off and this is not a problem but the battery pack is a little bit on the heavy side compare to others though the size is perfect. It resembles the size of a larger cell phone. I have another one that is a little longer, about half the width and probably 3 times as fat so the size of this one is great. It charged my phone in probably less than half the time as when I plug it into the wall cord. The 25800 mah will give me lots of charges before I have to recharge the battery pack. It does have different colors on the power button that tells you how much power is left which is ok but for me it would have been nicer to have 4 little lights that show the level of power left like my other packs. That would be the only thing I don’t like about it but that does not affect the efficiency of the battery pack. And amazingly they have a 24 month warranty and 100% money back guarantee. Sometimes you are lucky to get 3 months warranty.

At first this product was absolutely perfect- I tested it a few times before traveling with it just to make sure it worked well and I wouldn't be stuck with a non-functioning charger when it came time to travel. After about a week of using it, it stopped holding its charge and it doesn't always work with its wall charger. I would plug it in and wait for it to be fully charged, throw it in my bag to take with me for the day, and when I used it, it only gave me about 20 minutes of charging before it was dead. Then it started that when it was dead, I would put it on its charger and after about 10-15 mins, it would just stop charging. Not fully charged/ done charging, it just stops taking in charge. Wouldn't repurchase.

I love this portable charger! I gave it to my husband for Christmas because he would forget to charge his phone at night. I use it more than he does. My daughter had one we bought from Target and the charge didn’t last long at all. This has charged my phone at least 4 times before I needed recharge it. I would think every time I used the charger, is this going to charge and sure enough it would. Very pleased! Its the size of an iPhone 7 plus. But a little more thicker and heavier. It’s not something I would put in my pocket. I love that if I am talking to my kids on the phone and my battery is low I am not stuck in my bedroom sitting on the floor while talking to them. I can still move around. I use it while my kids are at their sport practices working outside or another part of the house. I love it.

The battery pack lasted for a while but it finally came to an end. Would recommend!

It worst best on low powered items. Anything else and the charge in the power bank will drain very quickly. Also takes a long time to reach fully charged.

I bought this to help me to charge my cell phone and IPAD and it has worked flawlessly since the very beginning. So far I've charged my iphone 6s plus 3 times fully and my Ipad air complete 1 time and it still had almost some power left in it. The charging time took me 6 hours and It has not given me any problems at all. The only thing which may be considered a "negative" about this portable charger is the color tells you when u need to recharge the battery. unlike other brand which show the battery % in either numbers, or dots. This battery % are in colors. from White 100% / blue 75% / Green 50% / red 0 - 25%. But this battery is very small slim compare to my other batter with the same mah. So it is great for travel.Overall, this is a great buy for its price and size. Would recommend.
