QuantumZERO Standby Power Bank [with Premium LG Batteries] (10050 mAh)

This one burned my wireless head phones, please don't trust your expenses devices it,since return window is closed I would have to bear double loss.

After 11 months of use still Superb working. Nice quality. We can charge a 3200 mah phone 5 times without using the phone. Charges fast eventhough no fast charge. 1st class product. Dont buy cheap Chinese ones. which will damage your phone. Free cable also. Small in size like 10000 mah. if u remove and connect the phone again charge will drain little like every powerbank. For this price they should fix this. See the pics i abused it dropped it. I use it everyday very heavily atleast 4 5 times a day because im free all day long. It has a flashlight too.

Pros:1. Works on OSX Sierra / Windows 10 / Ubuntu 16.10.2. Simple Operation3. Supports a. Samsung 240 Evo SSD b. Seagate 160 / 1TB 7200RPM Drive c. WD Black 2TB 10000RPM Drive4. Ability to use 2TB and 1TB together.5. USB 3.0 Transfer rate is good.Cons:1. Hot Swap is half baked. You can swap in and out harddrives, but on mac with Tuxera NTFS the other drive is also ejected. We need to be very careful while using hotswap.2. USB 3.0 Type A on the back of the device. Difficult to get new cables3. Power button is plastic-like4. Wished it had an ethernet portWarning:1. Do not lose the cover, it should be used to cover the device when not in use. Its not an easy job to clean the ports if the device is not covered

Does not quick charge. Fake claims. Probably paid reviews. Too expensive. Worst product. Compared the charging speed with mi 2i 10000 mah powerbank. Very dissappointing.

Look and feel:The power bank is built very sturdily, and it feels very good to hold. It's a little heavy but that should be expected of it due to its large capacity. Personally I think the weight just adds to the premium feel of the product, with the dark grey metallic finish.There are 2 usb ports (1A and 2A), and one Micro-USB port for charging the power bank.There is a blue led indicator, which shows the battery percentage left in the power bank.Performance:The power bank charges quite fast straight from the wall.The 2A port charges my phone with fast charging, and takes just as much time as it would for me to use a power brick from the wall.The charger can charge my phone around 5+ times, which is fantastic value, considering similar capacity power banks generally cost twice as more.Overall, an amazing product. Highly recommend. <DISCLAIMER: READ EDIT NOTE>EDIT: After 4 months of use, the 2A port has started to malfunction, with only the 1A port properly functioning.Furthermore, after charging the power bank occasionally fails to turn on. The only way to turn it on is by briefly plugging it back in.3/5, still a viable option.

Very useful USB hub as my laptop has only one USB 3.0 port and I was facing difficulties in using multiple USB 3.0 external hard drives. I tried connecting 4 USB powered external hard drives (two 4 TB & two 2 TB) and it worked smoothly. And I also tried transferring data within the hard drives to see the speed and got around 40~130 MB/s transfer rate (files varying from 500 MB to huge 30 GB). For convenience, I will list the Pros of the product so other people can know what they should be looking for -> Strong aluminum body which dissipates heat quickly> Sturdy and stable USB ports> Greed LED indicator turns on when connected> Can connect upto 4 USB powered external hard drives (I did it myself)> File transfer rate is USB 3.0, not only from your internal HDD to external hard drive but also from external HDD to another external HDD too. (depends on file sizes though)> About 1 ft USB cable is enough for comfortable placing of HDDs.> 1.5 year warranty as stated by seller (hope we don't have to get to that part)I would say this USB hub is worth the price because it gets the job done.Note: Don't try to connect power hungry USB devices like USB fan or anything as it only supports .9 A current max.

A blessing for those trying to run Windows 7 on a modern motherboard and trying to connect USB 3 peripherals. Speed is decent, not too much loss over the native ports. Would have liked a bus power option, but at the price one really can't complain. I was expecting slightly better build, but it's not too bad. The cable really needed to be longer. it just about reaches the top of an ATX case when running off the ports in the middle of the motherboard.

I tested external HDD usb 3.0 ..tested ...reading and writing speed 45mb to 55mb ...speed is not so great if u compare to transcend brand....usb hub.....I'm expecting more speed ...will test pen drive 3.0 then will updateupdate: something wrong with my laptop usb 3.0...i tested with desktop pc usb 3.0.....external hdd,usb pen drive 3.0 etc and its working very good speed 95mb to 105mb....so im giving 5 starthumbup

It does what it is supposed to do - only thing is that I order the EU version instead of the US version.. but I was lucky enough that I actually had a converter for it...

We charge two IPhones and two Kindles simultaneously with no problems. The charger does what I would expect from it.

Charge at the same time.

For 5 stars include a us power adapter

This does exactly what it is supposed to do by providing multiple plug-in places for our apparatuses especially when traveling​ and not sure what will be available to plug into.
