This could potentially be the best portable battery charger that is out there. It fits great in my pocket next to my Galaxy S6 edge+ and charges it up quite fast. The built-in AC plug and Micro USB cable just make sense and are the best features along with the 4000 mAh capacity.

That being said...after only a few weeks (maybe 3 weeks) of light usage, the built-in AC plug has failed. This is one of the best features of this battery pack! Unfortunately, it was only good for a few charges and now I am committed to charging my battery pack with a USB-to-micro USB cable (the old-fashioned way). I liked the idea that when I needed to top-off the charge I could just find a wall outlet wherever I was and just plug it in. Now, I would be forced to carry a charging cable around or plan ahead by charging my battery pack when I'm at home. And who wants to plan ahead...I mean, isn't that why we would want a portable battery pack anyway? So that we could minimize the amount of time we have to think about the battery level in out electronic devices and spend more time thinking about...well, something else?

Anyway, if I weren't having this problem with my portable charger (or if the seller were to make it right), I'd be more than happy to get this review up to 5 stars...because let's face it, this would be a great product at a great price.

One of my favorite purchases this year!
I spent a day in DC on a walking trip with coworkers. We took pictures and videos to our hearts content, until we realized that drains phone battery so quick. By the middle of the day, we were scouring for wall outlets to plug in our phones. Each stop, sharing 2 chargers for 4 phones, we'd all get maybe 20% and then continue on. Eventually looking for more outlets shortly after.
I needed a solution, and this was exactly it.
Rather than searching for an outlet, this pack gives plenty of power for my iPhone 7+ to get 30-50% charge. And when I do come across an outlet while at a restaurant or extended stop, I can just pop out the charger's plug, and top it off. No longer needed to carry around a wall plug with this built-in one!
I'm surprised more battery packs don't make them built-in!

Nice design, sleek shape fits well in my purse. Just note that the attached charger cables for NOT for iPhones. You need to buy a separate one for the lightning chargers.

We got this portable charger after we went hiking and both our phones had died and we decided that wasn't something we wanted to happen again with how far we usually hike. We have used it quite a few times since, between hiking and keeping our phones charged while shopping and our son wants to drian our batteries with Puppy Dog Pals videos. We highly recommend.

Bought 2 of these specifically to charge my E-cigarette (250 mAh, 4.2 V DC) batteries in remote locations having no electricity. Did a test on both chargers after insuring they were both charged completely. Found each charger would charge one of the E-cigarette batteries 7 times, averaging about 1 3/4 hours for each charge. Realizing reporting charging an E-cigarette battery isn't necessarily politically correct, it is something that wasn't addressed in Customer Reviews so thought perhaps this info might be useful for those of us still wishing to enjoy old habits. Intend to also advise Tzumi.

What a great charger! All in one: contains plug and cord! It charges my phone FAST, with enough juice to charge another phone. It recharges almost as quickly, ready to go again in a couple hours or less. I love this color - no more arguing if that's mine or his! I ordered his in black.

Update: I've had this charger for over 4 months and use it 3-4 times a week. It's still awesome! I'm ordering more for gifts!

When I received this product, I immediately charged it and it worked perfectly with my cell phone. I did not need it for a while. When I did need it on Memorial Day weekend it was fully charged but did not work and would not charge my cell phone. I had only used it once. Now the return window is closed and I am stuck with a non-working item and not happy at all. I would not recommend buying this.

I love this product, at max capacity it usually provides a full charge to my Samsung Galaxy S5. The nice thing about this compared to some other pocket chargers is that you don't have to worry about carrying around a small USB connector to charge your phone - there is one that is attached to this phone so it can't get lost... however, you still have the option of plugging in a USB to charge something else. My only complaint is that at night, the blue lights that signify charging are very bright - I had to cover them up with a small yellow sticky note, which works but the power bank is so powerful you can still clearly see the light.

I especially like the LED status lights. Not something I want to haul around on my person, but definitely useful in a satchel for business trips or a backpack. I bought the higher mAh because of reviews saying the lower mAh did not deliver a full charge to the phone.

In the past week and a half alone I have found myself 5 miles from my home with a dead phone. The babysitter would try calling. My kids would call, my husband.... I charged the portable charger and then promptly dropped it into my pocketbook. 3 days ago I found myself with a dead phone once again! I started panicking and then remembered about the portable charger in my bag! By the time I got home my phone was fully charged and it still had 3 lights (3 charges left inside it). The charger is extremely portable, light weight and lightning fast!
