Questions & Answers

Is this compatible with pass-through charging? In other words, can you use it to charge your phone while also charging the charger?

Although this portable charger is capable of doing so, we do not recommend it.

What is the weight of the object?

The weight of this portable charger is 410g.

I couldn't get it to charge my Samsung 8plus Android phone; it gave me an error message saying to check the charger, even though it was plugged in correctly. How should I proceed? Is there anybody else here?

I'm sorry for the inconvenience. Could you please try another charging cable to see if it works? If the error message persists, you can contact our customer service representative for assistance.

Does it work with any phone?

So, you can see that it has a USB port and that it works as long as you have a USB charging cable. We've also thrown in a micro USB charging cable for you.

I'm really annoyed because I bought two of these and now I'm going to have to return one of them
4/5

The first couple of times I used it, it worked perfectly. I had plugged in my phone the day before and discovered that it had not charged at all after two hours. I figured it was possible that the charger wasn't turned on and I hadn't noticed. I plugged in another phone today, it lit up as it began to charge, and when I checked on it an hour later, it had stopped charging. I changed ports thinking that might be the problem, and the charge went from 49% to 54% after 90 minutes. I then decided to simply return it, only to discover that the return period had expired the day before. I'm irritated because I bought two of these and now I'll have to go out and get new chargers. SAVING MONEY IS THE BEST THING YOU CAN DO! br>br>Recent changes: br>br> Rita got in touch with me almost immediately after I posted my review. Rita was meticulous, prompt, and accommodating. I received a full refund, and Rita followed up with me to ensure that my refund had arrived and that I was satisfied. For the sole reason of customer service, I have upgraded my rating from one to four stars.

Excellent charging time! I charged it overnight (12 hours, as instructed by the instructors) and used it to charge my phone for the entire weekend camping
5/5

The charger did not need to be recharged, and when I returned home at the end of the four-day trip, two of the five lights were still lit, indicating that there was still some charge left. br>br>Like all chargers, it's a little on the heavy side. I've had four others that were heavy as well, but none of them compared to this one. We were out sightseeing, and I was using my phone as a camera and video recorder. With my phone, I record a lot of video and take at least 100 photos per day. My phone's battery is nearly depleted at this point in the day. I plugged in the charger once I got to 30 I got to 30 I got to 30 I got to 30 I got br>br>This charger worked great for charging while I was still using my phone's camera. I'm glad I didn't miss out on any amazing shots. br>br>I also used one of the multiple ports to charge another device, and both of them charged as if they were plugged into a wall outlet. br>br>When I need a replacement, I'll buy it again.

Charger with a lot of punch The charger is larger and heavier than I expected, but it charges so quickly that I'm amazed
5/5

It takes some time to charge the actual charger, but considering how long it lasts, it's a great deal!.

The Port of Charging is flimsy
3/5

***Update: I received a call from the company. a refund or a replacement was made available. I asked for my money back. It was never given to me. On July 29th, I was displaced by the Carr Fire. I didn't follow up with Amazon because my world had been turned upside down. I'm sorry, but I'm also sorry for the company. PLEASE! br>****DO NOT PURCHASE THIS ITEM BUYING FROM THIS SELLER IS NOT A GOOD IDEA! *** Please contact me via email. The rest of the story will be told by me! br>The port from which it charges is extremely frail. The charging cord was extremely short. It slid down because I had to prop it up to get to the plug. The universal port was no longer charging, so I had to go out and buy a new one. get an i-pod cable phone. I won't be able to charge it unless I have that cord with me. To say the least, this item is inconvenient. br>I do not recommend it. I'll buy from Anker again next time because I was trying to save money and it backfired!.

I'm not going to charge
3/5

The first time I charged it, it worked perfectly, and it lasted me a full week of Pokemon Go play! That alone would have prompted me to award it a perfect five-star rating. But now that it's been a week, I can't seem to get it to charge. I've tried 5 different chargers and every outlet in my house for the past 7 hours. It is not going to charge. I'm completely depressed. I'm at a loss for what to do!.

IT Works! I tried this product because I needed a portable charger for my iPhone
5/5

It was a little heavier than I expected when I received it, but I could live with that if it worked as advertised. I completely charged it, and from there I was able to charge my iPhone 6 times from it, each time my iPhone was almost completely dead ( like at 2010% battery). It appeared to charge my phone quickly, which is nice; however, as I previously stated, I wish it wasn't so heavy.

Solid and appealing
5/5

This power bank is a lovely, well-made item. The initial charge took an overnight to complete, which was simple enough because I charged it at the same time as my phone. We chose this over lighter weight models because it can fully charge multiple devices, which is useful for us because we attend several all-day sports tournaments with three toddlers in tow and enjoy weekend camping trips without access to electricity. It will be updated in the future to reflect the product's longevity, but based on my recent experience, I'm pleased with the feel and limited use I've had. Make no mistake, this isn't something I'd keep in my purse on a daily basis due to its weight, but it's something I'd toss in the diaper bag for a day trip somewhere.
