onn. Dual-Port Portable Battery, 3x Charge, 10000 mAh - Aqua

This portable battery has a huge battery and will charge my phone multiple times before needing to be recharged. It charges at about a rate of 1% per minute, which is definitely an acceptable charge rate, especially when using the phone while charging. It charges my phone around 3-4 times before needing to be recharged itself. The only thing that is a little frustrating is that the battery itself takes around 20 hours to recharge from 0% to 100%. So when it is dead you have to wait quite a while to get the charge back up again. Other than that, this portable battery is a beast, slightly heavy but not uncomfortable to hold. Make sure when charging a phone to press the button otherwise it will not charge your device and pressing the button will also show the percentage of power left on the portable battery. Very convenient for mobile gaming and for use at places where you can not get a hold of a wall charger for your phone.

The juice onn. portable battery is a reliable way to carry an extra charge for your USB devices. It is sleek, comfortable, and about the size of a smart phone. It has two ports so you can charge two devices at the same time. It comes with a foot long charging cable and instructions on how to charge the portable battery. I am relieved to know I have a battery to keep my smart phone charged especially when I am on the go.

If you are someone who travels frequently, this is a must have in your carry-on or whatever bag you will have with you, just make sure you take this ! It will be a life-saver if you do not have access to an outlet to charge your phone. First of all, the battery pack will allow you to fully charge your phone about five times before it needs to be recharged. Here is something to keep in mind - the battery pack takes about 14 hours to fully recharge, so I suggest leaving it charging overnight. I have a samsung note 9, it will not fast-charge the phone, but will charge it in about 2.5 hours. The battery pack has a little led screen to tell you how much battery is left. I will never travel without this again !

Excuse the litany of numbers, but I wanted to be precise in evaluating the capacity and usefulness of this rechargeable power bank! I was quite pleased. First, the fully charged battery was used to charge an iPad 10 that was fully discharged. It was interesting that the percentages were almost exactly diametrical at the end with the iPad showing 99% and the battery at 1%. Time elapsed: four hours… To recharge the power bank from 5% to 90% took almost 5 hours, but it went to about 50% in two hours. So, like phone batteries, the nearer a full charge, the slower the recharge. … Charging an iPhone 10, starting with the phone at 1% and the battery at 100%, resulted in the phone being 94% charged after 1.5 hours. However, the battery was at 78%. Yay! This means that you should be able to completely recharge a phone at least 3 times before exhausting the battery. … Lastly, I plugged in the power bank when the iPad was at 10% and the bank at 43%. After 1.4 hours of constant use (surfing, not streaming), the iPad had moved up to 30% charge while still leaving 5% on the power bank. … A digital display of the power level is a great idea... However, you must provide your own lightning cable for Apple products... Still, the numbers are convincing. Plan ahead just a bit and you can keep everything charged and ready to go!

When I first plugged the power bank in before bed there was an obnoxious blinking light I wasn't expecting. Then I realized that anytime it is plugged in whether charging itself or charging another device it will show the percentage it is charged which is useful. At night when I am charging I just tuck it slightly under the bed so the light doesn't disturb my sleep. It charged itself up to 100% in like 2 or 3 hours which is good because I can plug it in while getting my household ready to leave and by the time we are ready the device is charged. It has 2 ports so it can charge 2 devices at once. It charges devices fairly quickly which is great because I was able to keep my phone and my daughter's tablet at 100% throughout the day by taking turns plugging each of our devices into the power bank when our battery life would get low. I have used the device for 12 hours straight to charge devices throughout the day and have yet to see the power bank be depleted of it's battery life. One day it got down to about 25% by night fall after being used all day. I am really pleased with how well this device charges my devices on the go. It is by far the best power bank I have owned. It is a bit heavier and larger than most power banks. I have a galaxy s10 (the smaller version of the s10) and the power bank is almost the same size as my phone and about the same weight. Most power banks are smaller and lighter but they also aren't as powerful as this one. One of my photos shows the size of the power bank on comparison to my daughter's tablet.
