mophie Powerstation Plus External Battery with Built-in Cables for Smartphones and Tablets (6,000mAh) - Space Grey

Perfect solution. The battery in my phone (Samsung Galaxy S4) typically lasts all day where I have good coverage, at work & at home . However, when traveling in the US and elsewhere where coverage is poor or when using Google maps & GPS extensively, my battery last only a few hours. Outlets in airports are often fully occupied, some aircraft still don't have outlets at every seat and of course if you are unplugged if walking or hiking. This Mophie solves all of those problems. About the size of my phone, it can recharge it fully 2 to 3 times. The on-board cord with a micro-USB tip can never get lost. There's allow a tip for iPhones that is stored magnetically if you're using the USB tip. The cord is sized so you can easily stack your phone & the Mophie in your pocket or in your hand while charging. 4 LEDs indicate the charge remaining.UPDATE Apr 2018: Loved this product, beautiful design, worked well with my Samsung Galaxy S4 and S8 with an adapter. Unfortunately I left it on a plane returning from a overseas flight. I'm buying a replacement with a USB-C connector to match my Galaxy S8. Doesn't do Qualcom Quick Charge but I consider this back-up power & power source for remote travel so quick charging is not essential to me.

I love this charger because it comes with the switch-tip cable that lets me charge my personal and work phones, and the array of accessories I use (wireless earphones, tablet) without carrying around an additional cable. The battery life is perfect for regular office and personal use, and it's a reasonable weight for the number of charges you get out of it (typically 4 for me). I always get complimented every time I take it out to use it or loan it to a friend.

This one is very nice looking but didn't last as long as the others. It's still nice to have though.

I Love the fact that it can fit in my pocket because its nice and thin with a long life off of wall charger and the built it usb cord is a life saver i don't have to walk down the street with a cord dangling from my hands and or pockets its worth every penny spent and im going to buy. A few more for some friends of mine thats how much i love my purchase of this particular item

This product is lightweight and convenient. I have not been using it for a long time so I'm not sure about duration but I will say the charger works and charges quickly. The only downside for my phone is that i need to take my case off for the charger to stay in and actually charge. Overall good purchase

I’m always skeptical at how well a powerbank will perform. I’ve used mophie battery cases in the past and decided to try this product as I was looking for something to charge multiple devices. Once it’s fully charged, I can typically use it to charge my iPhone 11 a few times throughout the day and not need to charge it for a few days. The built in cord and adapter for micro usb/lightning charger is pretty sturdy and comes in handy, plus not having to worry about having a cord is nice.

I have 3 (2 for home/1 in my car) now and have given one to every single family member and person I know. (I have been using a Mophie for a few years now.) They all love it! I'm a realtor and could not live without my Mophie. I tend to run my battery down quickly because I'm on the phone so much. I just plug my phone in, I can walk around and I'm good to go for hours. I originally purchased one at Verizon to help save the battery on my phone while charging in my car.. It keeps my phone from getting hot when it's being charged. It charges so fast and if you've ever heard the dreaded sound that your battery is about to die - no fear - Mophie is here! Best thing ever invented!

This is my 4th battery in 6 years. The first two replaced by Mophie. Each time the connector stops making connection or stops taking a charge.This one is heavier duty which hopefully helps because it’s much heavier to carry/hold. Maybe I should get a different brand if I’m replacing this frequently but I guess the devil you know is better than the devil you don’t know.
