UPDATE 5/24/24 - I had the same problem with the replacement sent by the seller and, since my purchase was still under warranty, I contacted the seller again. It only took 2 days for me to receive my replacement chargers and so far, so good! They both charged fairly quickly, and I was happy with how fast my phone was charged. My fingers are crossed that these will have a better outcome than the previous 2 sets. UPDATE 1/19/24 - Upgrade from 1 star to 4.5 stars (rounded up to 5 stars) I contacted the company and told them that my 2 chargers had quit working. They sent me 2 replacements very quickly, and after 2-3 weeks, I'm very happy! Both chargers work great. I recommend this product and this company! UPDATE 12/23/23 - After 3 months, these are useless. They take a long time to charge, and don't hold a charge for more than 15 minutes. When I plug either of these in to charge my phone, they charge for maybe 10-15 minutes and then the chargers need to be recharged. And my phone is only charged a little bit. I'm going to try to contact the company, and will update this if they help me out. But for now -- A WASTE OF MONEY! First of all, I purchased 2 lightning cables for these chargers because the cords included are NOT lightning cords (as stated in the description). Both of the chargers worked great for the first month, then the white one quickly started slowing down . I can charge my phone when it's at 50% to 100% in about an hour and a half, then the charger needs to be recharged because it's down to one light. This will usually take up to 3 hours. The black one started to slow down about 2 months after buying them. It charges my phone fairly quickly, but the charger battery is drained after one 3/4 charge of my phone. It seemed like it was a good price for a good product, but not if they stop working after 1 and 2 months AND having to purchase lightning cords. Looking for new ones to purchase. I would NOT recommend these.

Great chargers! 2 for the price of one!! Nice and compact and works very well.

After having read some of the negative reviews, I was a little skeptical about ordering this. However, I am very pleased with the product. I have not been paid nor received products to write this review. I don't write many reviews, but when I do, I try to do an in-depth evaluation of them. In my testing, I used my iPhone XS, iPad 6th Gen, my Kindle Fire 8 inch, and my wife's iPad Air 4. About the battery. It's not very clear from the website or the instructions on what the ports do, but the information is there. It would be better if the company printed INPUT or OUTPUT on the battery itself. To summarize, this device has 2 INPUT ports (to charge the battery pack), a micro-USB and a USB-C port. The USB-C cannot be used to power a device. To test this, I plugged a USB-C cable into my wife's iPad Air 4, and the iPad started charging the portable charger. The 2 USB-A ports are what are used for charging devices. Charging times will vary depending on if you are using the device while charging or charging with it off. Some reviews said it will only charge their device once. It's important to note, this is only a 10,000 mAh battery. My iPad Air has 8800 mAh battery. The battery pack has only an 80% efficiency rate (no batteries are 100% efficient) so you will only get about 8000 mAh from it meaning it will charge my device only once. It will charge my phone almost 3 times however. For tablets, if you want to charge more than once, then a larger capacity battery is needed. To properly use a battery pack, let you device run down some, to approx 50-80% before using the charger. IF you fully deplete the device, it may not be able to power the dive and charge it at the same time. Now for the tests on each device: Apple iPhone XS It charges my iPhone while using. It charged 1% in about 10 minutes. While the phone was off, it charged 10% in under an hour, but my phone was at 88%, so it was near a full charge. It would charger quicker if it had a lower charge. Apple iPad 6th Gen This charged my iPad while using it. It is not fast, but it will provide a slight charge while using. While off, I gained 30% from 36% to 66% in 1 hour and 15 minutes. Apple iPad Air 4 Apple's new iPad with a high resolution screen and fast 8 core processor for CPU and graphics, the battery will only hold a charge, this portable charger will not charge the iPad while using it. While off, it charged the battery 10% in an hour and 15 minutes. It is important to note, you will have to get a USB-A to USB-C cable to charge newer generation iPads. If you plug the Apple cable with 2 USB-C ports into the USB-C port on the battery pack, the iPad will charge the battery pack. Kindle Fire 8 Inch The device charges while using. Due to its smaller battery capacity, it charged about 10% in 15 minutes. As mentioned before, this is great value for a battery pack for smaller devices. It will power tablets as well, but for devices with large capacity batteries, it will be very slow, and only provide one charge. I've only had the device 1 week, time will see how well they hold up.

This stuff is usually a hit or miss deal. Mostly a miss especially when buying online but this time it was pretty great. I have been able to charge this in about an hour and a half and it lasted hours for one phone or it will last at least 3 hrs for multiple devices. So far it accepts adapters and spliced chargers and charges basically all of our phones & tablets with no issues. *Update... So the white block seems to be great and holds an awesome charge, the black block doesn't fully charge to the last light and so I get less charge time from the black one. Just be careful and double check the charging packs when you get them not just from here but anywhere. Just make sure they work to full capacity. I was a bit excited to have extra power for my devices and didn't take the time to notice the difference between the two blocks. They are still very good for the price but definitely I would want the two to provide equal power supply. In the end they are nice looking and seem well made. I guess sometimes you get some imperfections with some items. I won't be returning because the process is just time I don't have any it does still work,it's just the one black block holds less charge than the white block they sent. 🤷

Like them, friend of mine have the same exact thing for 5 years and it’s keep battery life for a long time and charge fast so I decide to get one too.

I’ve been using this USB portable charger for months, and it’s a lifesaver! It provides quick, reliable charging for my phone and devices whenever I need it, whether I’m traveling, commuting, or just out and about. The compact design fits easily in my bag, and the fast charging capability is a huge plus. I also love that I have it on auto-ship — I always have a backup ready to go. Durable, efficient, and super convenient — highly recommended for anyone who needs power on the move!

If the units had both worked this would have been a good buy.

Defective charging bank. Terrible customer service

I bought this two pack, one for my husband, one for myself. One works nicely, but the second one doesn't do a thing. It lights up for a second while being “charged” and the lights go out again. Plug it in to a device, same thing, the light turns on for a second, then nothing. Waiting for the day the one that works gives out.
