Web 1a is sufficient for most charging applications. A device being charged will only take as much amperage as it requires. The iphone will use max of 1a. If one port can supply 2.1a, then you can get 2a from it without any problems (you can get anything from 0 to. Many of those power supplies do provide two 2.1a ports for a maximum total current output of 4.2a. Web car charger 2.4a and 1.0a refer to the maximum charging current that the car charger can provide. Web a current rating of 2.1a means that the charger can support a max current of 2.1a. Web both ports will work with either device. Plug it into the 2.1a and it will use only 1a. If multiplied by the output voltage of 5v, it is the rated power of the.
If multiplied by the output voltage of 5v, it is the rated power of the. Web a current rating of 2.1a means that the charger can support a max current of 2.1a. The ipad will use max of 2.1a. Web 1a is sufficient for most charging applications. If one port can supply 2.1a, then you can get 2a from it without any problems (you can get anything from 0 to. By cutting back to a max total. If multiplied by the output voltage of 5v, it is the rated power of the. Many of those power supplies do provide two 2.1a ports for a maximum total current output of 4.2a. Web the difference between 1a slot and 2.1a slot is, that 2.1a slot provides more amperes, so it can charge your device faster. It can just as easily. If the output current is large, your load is easy to be full (short time), the output is small (long time) the charge stability is.
