What Customers Are Saying
Customers overwhelmingly praise this power bank for fast charging, compact design, and the convenience of a built-in Lightning connector. Most highlight its ability to fully charge an iPhone in two to two-and-a-half hours and recharge multiple devices on a single charge. Many appreciate the slim, pocket-friendly form factor and sleek appearance. The unified Lightning cable design eliminates carrying multiple chargers, which reviewers describe as a major improvement. A small number report charging failures or slow recharge times, though most consider it an excellent travel companion.

Would RecommendReplacing the one I bought in 2017. Protective case that also turns my iPad into a laptop (that is, it has a keyboard). So cool.

Piece of mind
Would RecommendNow I don't have to worry about my phone losing power, and I love that.

Don't expect it to last
Would Not RecommendWorked great... for a while. Then it slowly stopped charging and (now that the warranty has expired, of course) has to be charged all day just to charge a phone for 30 minutes. Be prepared to replace it in two years.

Fast, convenient and a good value
Would RecommendI ordered initially for my iPhone that didn't hold a charge. The phone was replaced, but it is so convenient to not have to plug the phone into the wall

Fantastic product!
Would RecommendLove this,. It always saves me from running out of juice when on the road, away from any power source. Gotta have my music all the time.

Great Charger
Would RecommendWonderful power bank. Recharges our iPhones many times faster than or old charger and/or using a wall plug charger. Very convenient size.

Not charging, just blinking one green light
I got this as a gift from my sis, I have only used for 3days and it’s not charging only blinking one green light after charging for several hours am really really sad.

Hi, Bunmmy, This is quite unusual as three days is such a short time for the power bank to stop working. Try using a different charging cable and ada...
BOOST↑CHARGE™ Power Bank 10K with Lightning Connec
Wish I would have bought sooner! Charges quickly and lasts a long time before it needs charged.

Charges my iPhone but sucks on recharging!
Would Not RecommendI read alot of other complaints on this charger. I like the fact that it has bailed me out a lot of times when my phone was near dead but when I am back home, it doesn't seem to want to recharge. It keeps blinking on the 3. And I have tried other charging chords and no luck. So... now what? I am afraid that others comments may be true!

Hi, This is definitely not the experience we want for our customers. We suggest that you try charging the power bank using a different cable and powe...
Comes in handy
Would Recommend[This review was collected as part of a promotion.] I use this power device when I know I’m going to be without a charger. It works very well! It does take quite some time to get a full charge on the power bank and I can charge my phone twice on one full power bank charge.

This product is rubbish = do not buy it
Would Not RecommendNotice how man reviews say one light blinking and wont charge. My son and both bought one with a week or two of each other and both units have this problem after less than 10 charges. Have tried different cables etc, but it’s clear that’s just rubbish printed to pretend to provide a response. It’s junk, don’t buy it.

Maintains a Charge
Would Recommend[This review was collected as part of a promotion.] This is such a great thing to have on hand. I tested this out once I got it and I must say that it held up wonderfully. It recharged my iPhone fully 5 times and I was quite surprised. I now take this with me every where because you never know when you will need it.

Works well
Would Recommend[This review was collected as part of a promotion.] In used this on a recent trip and was impressed. Charged my phone quickly and has a really nice design to it. The one thing i would say is that its a bit bulkier than my other portable chargers but i prefer how it looks

Awesome
Would Recommend[This review was collected as part of a promotion.] This little battery has a lot of power for how small it is. It's pretty heavy too. I like the fact that it has a wall charger with it and it charges my phone decently quick. I even had it charging my laptop.

Good powerbank but slow to recharge itself
Would Not RecommendI bought this powerbank about a month ago. It has fast charging which is very good. The only bad part, it takes long time to recharge itself. I get to recharge one to two dots out of four in over night charging. Used fast chargers but same. If you can handle slow charging of powerbank then this powerbank is for you. Output - Fast charging very good Input - Very slow charging.

Handy to have
Would Recommend[This review was collected as part of a promotion.] The PowerCore Metro Slim 1000 is my new favorite external battery! It's lighter and slimmer than others I own and lasts for several charges. I let it charge overnight and am able to use it for several full charges of my large phone. This device is handy to have when traveling as I like to watch movies on my phone while flying and this ensures I don't need to run to an outlet during my layovers. It's a great size and does exactly what I need it ...

Best quick charge
Would Recommend[This review was collected as part of a promotion.] I bought this high-speed charging kit because my phone is always dying at the ball games due to taking so many pictures and videos of my grandkids. This is a life saver! It's so easy to use and charges so fast. I have found my grandkids ate even borrowing it for their phones too. I love the design. It also has a very nice carrying bag. It's a great product for the price!
