This charger takes a long time to charge, yet fails to fully charge my phone. Bought it to go on vacation, fully charged it the night before but when I use it the next day it only indicates two lights. Also when you try to charge your device I have had the indication of "this device uses too much power" multiple times not even allowing it to charge my phone. It's slow (even with a good cord), dies so fast, and overall very disappointing other than its size. There are other options of portable chargers that are better for traveling. Would not recommend.

Does the job but...
Does what it’s suppose to be but recharges slow when plugged into the wall and it dies very quickly once it’s hooked to your phone. Bought it for my trip to Japan where it’s needed for your phone to be charged at all times. I’m sure you can get better else where.

Geniuenly the worst
If I could give less stars I would, as all the reviews say it takes FOREVER to charge, you can charge it all day and be lucky to get it half charged at best. As far as the speed at which it charges your device I suppose it's fine but honestly just get somthing else, maybe if it was five bucks I could see it being a last resort but at 20? It's a ripoff and a scam. Even a five dollar five below charger is better than this thing and those are made to be bad.

It’s nice and small but it’s take forever to charge and does not last long to charge. I plugged it in to charge my phone and it died at a full charge within 30 minutes and barely charged my phone. Would not recommend, huge waste of money.

Dont get it
The charge last for a short time. Forget using it for a full charge. Takes a long time to charge an iPhone. Gets hot immediately and takes a very long time to charge. I DO not recommend the charger. Spend more to get a better product. This is just bad.

Positive Charge
It works very well! When I first got it, it did not take long to charge all the way, so that was great for a quick first use. I didn’t realize it has a power button, so it got bumped off in my bag and stopped charging. But other than that it works great!

ZERO charge.
Bought this power bank while on a road trip. It had ZERO charged power… that wasn’t mentioned in the product description. I had to buy another one elsewhere.

Not the best option out tbere.
This power bank doesn’t hold a charge very long and can only charge my iPhone one time. I am giving this 3 stars because it does work just fine. I think there are other products that are superior to this one for the price point. I would not buy this again and would pick something else that had cords included and could charge my phone more than once at a faster rate.

Piece of junk, waste of money
I bought this for a small portable charger to use at Disney and planned to also have it for just days when I’m running around a lot in general. It charges the phone but very slowly. I’m unable to get a good charge out of it. And it dies so fast. I used it like once during the day each time and it would be dead and useless the next day. It’s like it dies whether I use it or not. Have to constantly charge this just to use it. I say listen to the low reviews and not the good ones because despite what the good reviews might say, this is pretty dang on useless as a backup charger since it’s probably going to be dead every time you need it. It’s just not reliable! I’ve not used it since the trip because it’s just crap.

Everyone complaining is expecting to much out of this GOOD & RELIABLE power bank
Not bad if you just need a top up in the middle of the day! Don't use your phone while it charges or you won't get much out of it (it's only 5,000mAh) & it's very obvious that it's only 5,000 so idk why people complain it won't charge their phone all the way some phones have more battery then this has lol. Reliable. Charge it when you charge your phone at night take it with you no problems I promise

Fabulous brand and product!
One of my favorite brands, it's a great small power bank to have around when I go out. I am able to charge my phone about one and a half! So convenient and travel safe! I can charge it with the cable provided and it comes with a small pouch. Amazing product! It also tells you how much charge it had left and when you charge it's fully charged it shuts off.
