Which "USB 5V-OUT-A" is rated 1000mA or the other "5V-OUT-B(2.1A)? Thanks

It is very doubtful that this cheap item is 30,000 mAh! Either somebody is lying or they don't know their math. [30,000 mAh = 30 Ah] Either way - Not believable. The reviews for this device, show its poor quality. This could indicate that they used lower-grade components (cheaper batteries, poor workmanship). Unreliable devices can cause much fustration!

in this picture the USB Port on the left is 2.1Amp and the one on the right is 1amp. The small micro usb port is for no-solar recharging of the unit, but I'm sorry to say my unit has stop recharging, either by solar or the micro usb.

I'm sorry but I just don't know, this charger I think doesn't even have a 30000 man capacity

Mine came with a "wall-wart" type USB power supply right in the box. Any 5v DC power supply that puts out 1.8 to 2.0 amps should work fine

110. But the USB unit was very cheap and was not providing power to devices. I returned the item

I am looking at the unit CA-2421 and it says It DC 5V 2.1A. I also can it charges really fast.

A USB port uses a max 500ma of +5vdc power = 2.5 watts. Thanks for using AnswerParty!

It is USB. The industry standard is +5 Vdc. USB always has been and always will be +5.

The output rating on this is 1.5 amps. Manufacturer notes, "Charge up to 2 small USB compatible electronic devices".

Power supply output: 5V 2500mANot sure how much power of the ~500mA from the PC USB port the hub is plugged into is used by the hub itself.Not sure about power supplies with versions other than the 13-port USB 2.0 hub.

MANUFACTURER RESPONSE: Thanks for asking! 2.5A is the total power available from the power supply- NOT the amount of power available to ANY ports. To say that another way, you would have 625mA (.625A) power per port max when using all 4 ports. The max current draw for a device complying with the BC 1.1 specification from any given port is 1500mA (1.5A). Please note this full current draw would be available to only one device at a time. When charging 2 devices simultaneously, we would expect charging at a max rate of around ~1250mA (~1.25A)- assuming no current is required by devices in the other two ports. Sorry we can't offer a more clear explanation here- USB charging is really a complex topic where devices from different manufacturers have very different behaviors. To top that off, many devices actually negotiate with the host PC to determine what rate to charge at, so behaviors on these will vary depending on whether a host PC is on and awake versus when there is no host PC or when the PC is sleeping.

Back of package says input voltage is 12V and the output voltage is 5V with port A at 2.1A and port B at 1.0A.

According to the very small name plate the rating is 5.1 volts at 0.85 amps. If you need more current many two port chargers deliver 2 plus amps. Search Amazon for "USB Charger" I have one from POWERGEN.

It is not listed on the device. wikipedia says "Powered USB is a proprietary extension that adds four additional pins supplying up to 6 A at either 5 V, 12 V, or 24 V." I have a 5V 2 Amp adapter whose connector is too small.Output of the cable reads 5 V. I had to check because I had not heard of 12 V or 24 V in conjunction to USB.

Usb is 5Volts with .5A maximum draw. My multimeter won't even measure the current it's drawing so I'm not sure the exact wattage. So by using the above figures... 2.5 watts maximum although I guarantee it's definitely less than that. Hope that helps. The actual unit itself has no power listing so that's all I can figure for that.

There are many USB chargers, max 2 amps. The 1 amps give a better charge, the 2amps give a faster charge. I used the one that came with my cell phone. All USB ports are supposed to put out the same voltage which is around 5 volts. So anything that will charge through a USB port will work.

I just confirmed that the Plugable USB 2.0.4 will power an RPi unit directly. The RPi only draws 5W, so it's safe.

yes, if its usb powered, guessing t100? cause my t100 charges off of most things, its just slow to charge when under 2.amps

I got this from amazon marketplace, it is prime eligible. Generic Premium External Power Supply 5v 1A 2A (1000mA - 2000mA) AC/DC Adapter, Plug Tip: 1.35mm x 3.5mm x 7mm, for USB HUB and 2.5-inch HDD Enclosure
