Question: Does it have led lights to give you approximate battery power remaing?
Document: Purchased for upcoming trip. Will update with more use.Straight out of the box and arrived with a full charge. All 4 indicator lights lit up. Looked over the directions and decided I better give it a quick test. Plugged iPhone into the port with a single lightning bolt symbol (directions call it a flash) with the 2.1A output, and plugged in original Kindle Fire into the second port with 1.5A Output and hit the button to turn it on.
The power bank is working fine.A bank's charge, last more than a week of my phone's power hunger.I give you FIVE STARS.
This periodically does what is supposed to do. Give your mobile devices power when you have no access  to an outlet! I normally get 3 full charges on a Samsung Galaxy s5. Or 1 full charge on a Kindle fire hd with some left over to charge the phone :) very handy especially when traveling! Would recommend to others.
Last night I plugged in my Android (Motorola Razr Maxx) cell phone and my Kindle Fire both at the same time overnight. They were both down to around 40% power remaining. This morning they were both fully charged and there were still 2 out of the 4 lights left on the EasyAcc. Apparently that means I can charge 2 things again without having to recharge the EasyAcc.
She wrote to me... &#34;dad... get prepared, work on your preparedness for the family.&#34; This promoted me that I need to do something because we live in one of the largest earthquake fault zones.Having some basic power for lights and communications I felt would be essential. I read the reviews on this and so decided to purchase because of portability, light weight, and overall effectiveness.
I'm using the same information that I wrote in my review of the Anker 8 watt solar panel since I use both of these items together to get the results I need:-----------------My daughter was caught in super typhoon Haiyan in Tacloban Philippines. It was a heart wrenching experience seeing so many people suffer. People desperately trying to charge phones, lights, so they had some morsel of power to live by.
I've used this more times than I expected since I purchased it, mostly to charge my iPhone and my wifes iPhone. It is slim and fits nicely in a backpack for travel or a deep pocket. It charges phones quickly and also charges itself quickly from a USB cord. The small LED lights on top show the power remaining and so far I've not depleted it below 50% - and with dual outlets it works nicely if you want to share some juice with a friend or neighbor at a table.
I like the look and feel of it. I also like the fact that there are some indicator lights when charging. I have not yet been in a situation that allows me to test how much charge this product will supply to my tablet/phone if battery dies.
Powerful enough that I could recharge my phone and use it at the same time. Some chargers I've used barely give enough juice to keep the battery from going down any further while you are using it and charging it at the same time.Originally bought this just for travel but plan on keeping it in my purse. Would use it in my car instead of the car charger as the car charger has the problem mentioned above.
I'm a consumer that is hard to please. ( Picky! ) But this item has everything to be pleased with and nothing that I could be picky on. It apparently will sense the charge of your smartphone and give it a rapid charge, then settle down to a normal charge and then trickle. The software to display I guess is incorporated into this battery pack. It looks really super also. My HTC ONE M8 was down to 68%.
Answer: Yes. I think their are 4 of them. Blue lights. They also blink and light up when charging it.
