EIGELIU Headphone Jack Adapter Cable Car Charger Dongle AUX Audio Jack Earphone Extender Jack Stereo Cable (White)

This is a really big battery and the features are largely great. Just a few gripes. You double tap to turn on the LED flashlight but there is no lockout for this feature. Several times it has turned on in my bag. Second, it auto turns off when charging, but that means when I travel if there is no suitable outlet and I plug in my phone will hit charged and then the unit turns off and I wake up in the morning and the phone has been discharging for several hours already. That said it is nice to have pass through charging and the display is nice and much more informative than the usual 4 blinking LEDs typical to these.

Using for about 7 days w/my new Canon 80D.Very satisfied.Actually became better after the 2nd charge!!!Has LED light, too..!!This large p-pack has 3-USB outputs & Pass-Through power/charging & is a must have if you serious.I use this p-pack with the Tether Tools Case Relay package which provides the camera battery replacement & allows the hot swapping of power packs if needed. Very cool, indeed (but, not cheap)...!Get the [Upgraded] Anker 24W Dual USB Wall Charger,... 5V x 4.8 x 2-USB outputs or equiv.If everything takes a dump, I'll keep you informed.So far, for $50.00 this is THE large and best featured power pack to buy and I did my homework..!! LOL!(other items not included in the $50.00)

I've had this pack for all of maybe 2 weeks and already it's been more than what I expected. I'm reading reviews about the "screen being too bright" or the flashlight being too bright. Are you kidding me? It comes with a nice bag...keep it in the bag while you're charging. Problem solved. This was a gift from my wife for Christmas and it's definitely my favorite. Charges super fast. I've been able to charge my iPhone 6+ & 6s repeatedly and it's still holding a solid charge. I had a long trip from Houston to Spain with 2 layovers....this thing is a travelers dream. I'd highly recommend it over and over again!

Had to use it for almost a week not consistently to drain it dead. Charged up to 100 Percent within 12 hours. Best battery I ever bought

Best battery I own. Love the smart technology that just picks out the correct amps and voltage for whatever I plug into it without having to remember which outlet to use. Love the "pass through" feature that lets you charge the battery while you use it to charge other things; it sure is nice to use a SMART battery instead of a dumb one. I have four 22000 mah batteries that COMBINED weigh about the same as this one, but even though they also have SOME smart tech, it's nothing compared to this. This batt may be kinda clunky, but the tech more than makes up for it. The flashlight feature doesn't work, but I dont care, I wasn't buying a flashlight - I was buying a battery.

If you are tired of going through lithium batteries for your ATN night scopes, purchase this and a coiled micro USB cable and you can be powered up for several days of hunting. My first six hours of hunting used 11% of the battery power. The temperature was 105°F and I probably would've had to go through eight AA lithium batteries. Hope this helps. As always, be safe. JJ

Had to send this back a day after I got it. The device itself looked brand new and was packaged nicely. However it took 8 hours to charge itself and could barely charge my IPhone 6 to 50% before it was completely out of juice. Completely useless as a battery pack. At least Amazon has free returns.

I LOVE this portable charger. I do business development for work and am rarely in my office as I travel majority of my day going from client to client. My girlfriend and I are avid Pokemon Go players and this is a heaven sent item.To put things into perspective, we took a trip to the ocean and rented a house in which the bedroom had no outlets. To charge our phones we both plugged into this and were fine for the entire three day trip without needing to recharge this battery. It handled 2 iPhones and my Apple watch all at once with absolutely no issue. I carry it with me in my backpack at all times now.
