Not all Apple and Samsung battery chargers built the same

If you've bought a few Apple or Samsung phones in the past few years you may have noticed different chargers bundled with your phone.  But what exactly is the difference?

Here is a comparison of the various current Apple power adapters:
ModelShort DescriptionConnectorPower OutputQuick ChargePackaged with
A12655W Small square iPhone charger (older model)USBDC 5V, 1 ANoiPhone 3G, iPhone 3GS, iPhone 4
A135710W Block iPad chargerUSBDC 5.1V, 2.1 ANoiPad, iPad 2, iPad mini
A13855W Small square iPhone charger (newer model)USBDC 1V, 1 ANoiPhone 4S, iPhone 5, iPhone 5S, iPhone 6, iPhone 6S
A140112W High power large block iPad chargerUSBDC 5.2V, 2.4 ANoiPad Air, iPad Air 2, iPad Pro

Here is a comparison of the various current Samsung power adapters:
ModelShort DescriptionConnectorPower OutputQuick ChargePackaged with
ETA-U90Blocky low end chargerUSB DC 5V, 0.7 ANoGalaxy S2

EP-TA10Blocky charger USB DC 5.2V, 2.0 ANoGalaxy Note 3, Galaxy Tab Pro 12.2 and Galaxy Note Pro 12.2
EP-TA12Blocky charger USB DC 5V, 2.1 ANoGalaxy S5, Tab 8.9, Tab 10.1
EP-TA20High end blocky charger USB DC 5V, 2.0 AYes, 2.0Galaxy S6, Galaxy S7

All this information can be found in small text on your power adapter. The output indicates the amount of power sent to the phone.  Both Apple and Samsung power adapters provide a USB connector to a microUSB cable.  Generally Samsung follows the Model number with "J" for Canada, US, Japan or "E" for Europe.

Using a lower output charger than the one included with your device may not work or charges your device very slowly.  For example the iPad Air charges very slowly with the A1385 and even drains faster than it charges if you're playing CPU/GPU intense games.

Using a higher output charger can charge your device faster such as charging an iPhone 6/6S using an iPad charger will charge from empty to full in about 2 hours.  However, be aware that using a charger that has a higher power output than the charger that
came with your phone may overheat your battery and may degrade the
life of the battery

Quick charging in newer devices make a big difference.  Charging the Galaxy S6 took 50% longer to charge with the EP-TA12 compared
to the bundled EP-TA20 with Quick Charge turned on.  So if you're looking for a phone that charges quickly make sure you get one that supports Quick Charge 2.0 or higher.
