Question: Is this device going to overheat batteries if used as a usb charging station for batteries that only require 500 milliamps to charge?
Document: awesome for a charging station for all items
So basically now I just plug it in and hope for the best because I cannot tell if it is charging or not. Like I said if one of the USB ports went out I would have no way of knowing because the indicator on the device may or may not come on when it is plugged into the charger.
The product does what is says but it could do a better job. I had a couple of tablets that were not charging with the OEM USB charger. As a result I thought I would give this a try. I wish there was a light to indicate when the charger was charging a device. The problem I have is that when I connect a table of phone to this charger it takes about 15-30 seconds for the device to respond and give a guestimation of how much the device is charged.
There are those tablets out there who require the data wires (D+ and D-) in the USB cable to be shorted before they'll actually charge at &#34;plugged into AC&#34; levels (in other words, &#62;500mA)--even if it's hooked up to a transformer block that can supply as many amps as the tablet wants. Many USB multiport chargers do not have those types of plugs.
Having to carry around 1 charger instead of multiple ones is a big plus, especially one where a regular power cable is used at the power receptacle instead of a thick unit. So far, I have no problems charging two tablets (both requires at least 2A), a cell phone (1A) and an MP3 player (500mA) at the same time. The charger does get a little bit warm when charging all those units but it is not uncomfortable to the touch.
If you were to fill all of the ports, each device will only receive a Amp at five volts regardless of how the port is marked. This is not a problem. In fact, it's a safety feature because the device has the built in logic to ensure that it will not over charge a device.For someone like me who has a tablet and a high end phone this has value because I can charge both simultaneously at full speed and still manage to charge a headset.
I have used this product for a few weeks and I have had no issues with it with it.. Seems to charge at a constant rate and no heat issues. the cord allows you to place it anywhere without having to have it placed directly on a power surge protector or a wall outlet.
Bought this to eliminate some of the clutter under my desk. I was able to get rid of the odd sized chargers and plug everything USB into this. Ports are labeled Android, iPhone, Samsung Tab, etc. The markings show what the port will charge optimally however you can plug other devices into them and they will still charge just not as quickly. The device looks good. It does not sit perfectly flat on my desk though. This is due to the rounded shape.
And, of course, those still charge anything else--unless there be the doppelganger out there of the tablets who require shorted data wires and instead require power on the data wires.Anyway, I also love the fact that the power cord is detachable AND replaceable by a standard C7 type connector cord. And this puppy just feels well-built. Been working fine for over a month now. Does not get hot and has no bright lights to make you think you've woken up to an alien abduction.
Wow, I love this. We used this in the motorhome to charge all of our phones and tablets at once. It works extremely well. There are outlets specifically for tablets and for phones. They charged quickly and without any issues. This is a huge space saver too. It feels very sturdy and well made. The whole thing comes in a small box and was easy to set up.Sample provided
Answer: No - I have not see any issues plugging in 0.5A devices (BT headsets) in a 2A port on this charger on both the device and charger. I have noticed the charger gets hot when I plug 3+ devices onto the charger but not unusual compared to other charging bricks.
