Bests & Worsts Reviews from Amazon

Using a professional watt meter to track voltage, amperage, and wattage, we compared the 25W charger that comes with the Note 10+ to this 45W charger. At no time did the 45W charger actually provide 45W. It runs at 24W at 380 mA almost the entire time while the 25W ran at 27.5W at 350 mA almost the entire time. What this suggests is that this charger is slightly more efficient and will use a little less wall power to charge. It will also likely generate slightly less heat. HOWEVER, on either charger it only takes about 20 minutes to go from dead to 85% (which is when the phone drops down to 10W on both chargers) This nets a potential time savings of one to two minutes. Please do not waste your money on this charger. For the Not 10+ you should be spending around $10-$20. We also tried plugging this into other non-note 10+ devices. None supported the higher amperage, lower wattage charging. Our assumption is that the note 10+ itself has software on-board allowing it to communicate with the charger. In regards to build quality, the charging block is larger than stock and comes with a thicker cable. While this may or may not be necessary for function, it did likely cost more to manufacture.
