Great Buy!

ZMI PowerPack was a great on a recent trip to Iceland. For several days, we were in a remote section of Iceland where there were no villages for miles. However, I was confident that I wouldn't run out of cell phone battery because I charged my phone on my battery pack when my phone battery was low. The battery pack worked easily and perfectly. It was easy to charge each evening, and I was assured that I had enough battery to last for an entire day. I am so glad I made this purchase. It went through security at the airport with no problem, and it made my trip much easier. I highly recommend this product.

Quality, enduring and affordable portable charger!

I received this portable charger as a gift from a friend before my trips in East Asia and Europe. While traveling I always need to make sure that once I am out there in the world, I have enough battery left in my phone so that I won't have problems staying connected to the internet, finding my way to the next metro station via Google Map and messaging friends etc. So ZMI 2-Way Fast Charging Portable Charger did exactly that - after charging over night with my MacBook Pro, I was able to use my phone without having to worry about only getting 20% left of battery in my phone. Great things about this portable charger: 1) Elegant design. It's thinner and smaller than most portable chargers I owned or have seen. 2) Great battery storage. I get it charged via my MacBook Pro overnight while traveling and I almost never ran out of power with my phone. 3) Affordable price. 4) Excellent quality. You can feel it when you hold it in your hand. It takes great engineering to do that.

Good buy! Happy so far.

2 day of owning this. Exactly what I am looking for. Light and sleek, and good price too. Instruction: 1. No power button, it’s automatic. 2. Button is for charging option. 2. Press twice for fast charging ( 4 flasing lights) 3. Press once for normal charging ( accending light )

The best 17 dollars I've invested in

The best 17 dollars I've invested in. Takes about 3 to 4 hours to fully charge this thing, but on a full charge it'll be able to charge most smart phones a good 3 or 4 times. It also has a fast charging option for those phones and tablets that have the feature. Very portable and lightweight. The charger is encased in a hard plastic shell, which is not the best design to take hard fall. However, it's shell also has an convenient anti-slip design to accommodate for this. This charger still holds it's charge after 6 months of consistent usage. If you want a good reliable charger with the fraction of the costs then look no further than this one.

Balance between weight and capacity

The main thing that pushed me to buy this power bank is the balance between the weight and the capacity. This powerbank is very light and thin, only 6oz weight and 0.5 inches thick. And It provides 10,000mAh capacity which is good enough to charge most phones 3 times. When I travel, with heavy laptop and all the other stuff, really don't want to bring a big 1/2 to 1lb power bank. It's hard to find similar product on the market. This power bank also comes many other good features, e.g. anti-slip, fast charging for supported phones, and small current charging for wrist bands/watches etc. Overall, I like this product very much with these features, and the price is good. One thing I'd like to complain is it only provides one output charging port. Sometimes it maybe inconvenient.

HIGHLY RECOMMEND!!!

The capacity of a powerbank is always an issue to me. Before I had this, I have to charge several powerbanks to make sure my phone would not be out of battery. But now I only need to charge one and it is good for charging the whole family's cell phones. It works perfectly with the LED light. I don't have to buy these expensive batteries. Instead, I just plug the LED light on this powerbank and all I need to do is to adjust the brightness.

Nice unit. Power or SOC button mystery solved

Nice unit, really nice and flat. Almost as flat as my iPhone 6 with thin TPU case, and approximately the same length and width. No documentation included. I went to the support site and there is no documentation, FAQ nor anything more than contact info. I contacted Support and within a few hours got an email with PDF attached, so I have updated/replaced my prior review, changed it from 4 stars to 5. Can't comment yet about long term durability. This power pack is auto-on and off. The button is not a power button, it is a fast charge button and also is used to show state of charge. The documentation of light next to the button is as follows: Blue light ON/OFF for high-speed/normal charging. NOTE: For fast charge capable devices, the light will turn on automatically or you can press the SOC check button to toggle high-speed/normal. For the rest, including iPhone/iPad, it's normal that the light stays OFF; rest assured that PowerPack always charges your Apple/Android devices at their fastest possible speed. Small-current charging mode: Double-click the SOC check button to enter the small-current charging mode, which best suits wearables such as Bluetooth earphones and activity trackers. The SOC indicator lights will be flashing in a round-robin fashion while in this mode. To exit the mode, single-click the SOC check button or wait till a two-hour maximum time limit is reached.

Great product with great price! I BOUGHT 5!!

I’ve had it for about a month or so and it works well and charges up within 6 hours using an ipad brick! It can give my iPhone SE 3-4 full charges! The only downside might be there is only one outgoing outlet so you can only charge one device at a time! Very lightweight and easy to carry around! I bought it in the colors black and aqua! Edit: my family and I use the chargers so often we actually bought 3 more, now we have 5 in total!

Love this portable charger

Love this portable charger. It's super slim and light and gives a fast charge. I originally bought this one https://www.amazon.com/gp/product/B013U3WNPI/ref=oh_aui_detailpage_o07_s01?ie=UTF8&psc=1 and was unhappy with how long it took to charge, not to mention it is a lot heavier and bigger - and more expensive! Definitely recommend.

Impressive performance in a perfect foot print

Having used this battery pack intensively for about a week, I would say so far I'm impressed. Here is a quick run-down of the pros and cons: Pros: 1. Super quick charge (< 4 hrs to full) but with surprisingly large capacity - enough juice to feed my iPhone 7 4X or roughly one light per charge cycle for my phone. 2. Having used plenty of portable chargers in the past, I've found those real tiny ones are pretty much useless while the bigger ones are often too thick or too long, awkward to carry with the phone. This one has got just the right foot print - it's a shade shorter and thinner than my phone (see picture), so the two stack up nicely and can be carried around together like good companions :) Cons: 3. I would have liked it even more if it were in white or a lighter color, which helps the battery pack stay cool, especially when you forget and leave it in a car under direct sunlight...
