Came from China so expect bad quality. It works but the charging ports are very temperamental. Have to have the battery positioned just right or it won't work, though it does charge well.

Works but is poor quality. Image flickers magenta.
I need to replace this screen, but I would have to pay for return shipping back to China in order to get a replacement. That would be expensive. So it was a waste of money.

Bought this item in November and already the charging port is giving problems.

After a couple months one of the charging ports stopped working. Within six months two of the ports stopped working.  Now, a year later, we are down to two working charging ports out of five.  One port failing I could understand, but over half of the ports failing is just the sign of a low quality product.

This came from China.  I don't have a problem with that, but it may help some of you determine the quality a little better.  This port cover is rubbery and flexible.  It doesn't fit the port snug enough for my tastes and neither does the headphone port cover.  Both pieces are loose only iPod nano and Touch 3.

This from China so the quality was not very good, look for a company that is American

I plugged it in for the first time, to charge it, and the percent of charge display flickers like a bad light bulb. That percentage never goes up. It was plugged in for about 5 hours. Maybe I got a bad unit, but I'm very surprised by all the positive reviews. I've requested a refund and I'm sending it back.

** Update 7/28
Seller contacted me and offered a replacement. They asked me to change my rating. I will do that if the replacement works.

** Update 8/7
The replacement came and it works like it should. The charging ports have different symbols on it which makes me think it's from a different production run. I don't really trust that it will last, but maybe it'll surprise me.

It's been working well for more than a year now. I have few chargers. This is the heaviest but it does the job.

I bought this thing almost two years ago. I use it in the most absolute emergencies, but it seems to work best with lower end phones that don't need to draw as much power. When I had a much cheaper phone back then, this served me well. Any other phone I tried to charge was not readily accepted by this power bank.

There's also the quality. When I received the power bank in the mail, it was wrapped in decent plastic. However, after I took the plastic off, I quickly noticed that there seemed to be glue oozing out the sides. The internal ports also move around! Sometimes I have to try and pull out the charging port a little so that I can actually charge the power bank! So, definitely could have better quality.

Not for US market buts seems to work but slower charging than oem

I honestly expected a little better quality feel to this product but you get what you pay for i guess. The good news is all the ports work. I was nervous about it working with my portable power bank and Type C cables but it does work.
The plastic housing is very thin and cheap feeling.

Doesn't come with a charger. Very very light. I don't like the quality of it but it works. It sounds good and it gets the job done. I wouldn't make this purchase a second time but I am happy that I have something to hold me over until I upgrade. My last set was stolen. I have had better ones. I purchased it item at a discounted rate in exchange for my unbiased opinion.

Charger works well however its flimsy and very easy to damage.  If you travel with this be extra careful.  The USB port is very fragile and easy to damage when inserting the cable.

First of all I like the item, and it works fine but the charging port, which i believe is a micro usb, has broken off from the circuit board and now won't charge. Its very fragile and the way its attached to the circuit board makes it prone to failure.  As it was out of warranty I took it apart and found as i suspected, charging device had broken off. I can't see how to repair it as its so small and no real way to reconnect it. I will just toss it in the trash as its not worth the money or time to repair it. I have to say that this is not the only item that uses this type of connection and I have had the same problem with other devices in the past. So I will say its the mini usb that is the problem, it needs to be attached in a better way to the circuitboard.

Its hard to believe that companies that use this mini usb don't know about its flaws. I see other people complain of the same thing happening to them with this product. I guess all you can do is get an extended warranty on anything that uses this type of charging system and be as careful as possible. That being said, I have an idea that this actually is a planned obsolescence feature as everything else seems to work fine.
I hate throwing good money away but what can you do ?.

Power charger itself is great.  Problem is that it shipped with a bad cable.  My wife went on a trip to China thinking she could use the charger to keep her phone charged.  No luck.  Not only did it not charge her phone, it drained the battery almost instantly.  Again, I can not fault the charger itself but the charger cables need to be quality control tested prior to shipping.  Could not test the unit as it came completely discharged so I spent nearly 24 hours charging to full charge.  Her flight left in the middle of the night so I did not have time to test.  I am not at all happy with this purchase.

it came in no box, just the shipping label on the package, and it sems to charge at like 0.5 amps on the USB ports.
has a funky plastic smell and feels cheap all around.
would definitely not buy anything from this lineup again.
cheap made in china product.

Not to be negative. However the part was coming from China. That wouldn't be so bad if it got here in a decent amount of time and actually worked. I got this thing and tried it on my XBOX One. Not only does it not work but it actually shocks you on three of the component jacks. I will not be buying anything from China again. This makes the 5th product I have bought that came from China that doesn't work as advertised.

The good news is that it appears to work so far.

The bad news is that the workmanship is horrible. Because there was a piece rattling inside the light, I decided to open it up. They crammed an AC-to-DC transformer into the back compartment without bothering to tie it down. The transformer barely fits into the back compartment and protection of the wires is non-existent. Mine did come wired with a 2-prong plug on the end of the cord so I did not have to figure out the wire color code.

I purchased this for outdoor use but now seeing how the rubber gaskets don't fit right and the back compartment is cracked, I think I will only use this indoors.

The box ships directly from China with no paperwork so just hope it works when you get it.
