Portable Charger Built in Two Cables Mini Power Bank Outdoors 9000mAh Ultra Slim High- Speed Charging External Battery Charger 3 Output & Dual Input with LCD Display for Android, iPhone, iPad（2.0）

UPDATE 7/12/20: Yep, still my favorite portable battery. My SE took a lot less energy to charge than my current iPhone 8, but the battery still gets the job done using no more than 20% of its power, usually less if you’re not using your phone at the same time. Just dropping in a year later to let y’all know it’s lasted this long!UPDATE 9/13/19: Okay, this battery surpasses all others I have owned because it lasts freakishly long. It fully charges my iPhone SE using ONLY TEN PERCENT of its power (or less!) Every time. Bigger phones take a bit more juice but it never uses more than 15% at a time to charge them. I hardly ever have to recharge it!UPDATE 8/10/22: Wow it's been 4 years and this battery still works as well as it did on its first day. I'm impressed that it can charge my iPhone 12 mini quickly just like the primitive first gen SE. I seriously don't think battery wear applies to this powerhouse.----ORIGINAL REVIEW: I still say that the best and most handy battery of all hails from iWalk (the geniuses who managed to fit three different charging cables in one battery AND with the charger built in) but this is a solid second best. I’m not a fan of how elusive the advertising was about the USB C adaptor; it’s included but has no storage slot on the external battery in case you’re wondering. Even so, this is the most powerful battery you’ll find for a size this small. I’m generally picky about these things and give it a thumbs up. It charges a pretty decent speed I would say and is incredibly light.

I have had my fair share of powerbanks. My first powerbank was one of those lipstick kinds with a very small capacity. Those ended up running out far too fast for my usage. The second kind I bought was an extremely large capacity bank over 20,000mAh. The powerbank lasted long but it was HUGE and felt like I was carrying a second/third phone due to how big, heavy and thick it was.This powerbank has good capacity that'll last me through the day or two and it's light and TINY. When I say tiny, I mean it is VERY TINY. It's a fraction of the size of my 20000mAh. I compared it to a switch joy con (if any of you have one of those, you'll know how puny joy cons are). It's hardly bigger than a single joy con. This is probably going to be my daily powerbank from now on. The lightness and tiny form factor make this a perfect daily bank. Also, it has a mini usb and lightning cable built into the powerbank. This is extremely important for me because I hate bringing my cables around with my powerbanks, and having loose cables in a bag causes the cables to break over time. Having it built into the powerbank reduces that issue. I'm really glad I found something of this size, it's really convenient.

I've had this charger for 2 months now and feel it's a good one overall.I like that it's compact, small for a 10,000 mAH charger.The digital display and built-in cables are very nice and useful features.However it is NOT a fast charger. I wish it was a fast 2A charger. The other portable chargers i have charge twice as fast.Also would be nice to have a magnetic surface on it, so you can attach it to the back of your phone case, while it's charging.

I like this powerbank because it has "build-in" charging cables. The charging cables can be easily pushed into the notch and leaves no clutter. The design is elegant and portable, which makes it smaller than my palm and as light as my phone. The battery life is real and can last a week based on my usage (almost a heavy phone user). It has both lighting cable and micro USB cable and can charge iPad and kindle at the same time. So far this is the best powerbank I'ver ever own. I plan to purchase more for our family.

I've had and used this for 4 years, still works as it did on day one and haven't broken the cables

I specifically bought this one because of the built in cord, so I wouldn't have to carry around an additional cord to charge my phone. After 5 months, the iPhone cord broke on the device, sadly. The bank itself still works, it's a really great charger, it charges my phone fast and holds the battery for a long time. Since it broke, I have to bring an additional cable with it to charge my phone, which is unfortunate, but it is still a good charger.Update: the whole thing stopped working completely. It won't charge my phone at all. Either the cable is broken or the charger is, but now I don't have a portable charger. ☹

Bought 2. Batteries have good solid build. Perfect size. Cables seem a bit flimsy but I haven't had any problems.After testing the battery, neither are even close to 9,000 mAh. But that's expected though...no battery will ever show total discharge of its capacity. I tested the battery few cycles. Included pictures are a good representation of the tests. Even though mAh is considerably lower than advertised, seller's description of the capacity (about 3x charge of iPhone 8) might be somewhat reasonable. I can charge my iPhone X about 1.8 times from 0%.Battery 1 - Problematic, might need to return.Total average discharge: About 4,500 mAhTotal average charge: 6,800 mAh.This battery makes a loud buzzing sound during charge sometimes. It also takes much longer to charge than the other one that I have - extra 5-6 hours for some reason. I tried different cables as well as different chargers with higher amps.Battery 2 - More consistent but lower capacityTotal average discharge: About 4,000 mAhTotal average charge: 5,800 mAh
