According to Apple’s website, iPhone 12 and iPhone 12 Pro can charge 50% in 30 minutes with a 20W adapter. Is it PD (power delivery)? And is it well compatible with the adapters on the market? I am curious as well. So let us test it.
iPhone 12 Charging Test
Test tool: Power-Z USB Tester
Cable: iPhone 12 original cable and Anker USB C to lightning cable
Test 1:
We used the Zendure SuperPort S3 65W GaN charger to charge iPhone 12. The voltage is 9.17V, the current is 2.24A and the power is 20.64W.
Test 2:
We used an Anker 65W Pod Lite adapter to charge iPhone 12. The voltage is 8.99V, the current is 2.00A and the power is 18.01W.
iPhone 12 Pro Charging Test
Test tool: Power-Z USB Tester
Cable: iPhone USB C to lightning cable
Test 1:
We used an Apple 20W power adapter to charge iPhone 12 Pro. The voltage is 8.98V, the current is 1.98A and the power is 17.81W.
Test 2:
We used an Anker Nano 20W charger to charge iPhone 12 Pro. The voltage is 8.87V, the current is 2.17A and the power is 19.29W.
Test 3:
We used a Nubia 65W GaN charger to charge iPhone 12 Pro. The voltage is 8.84V, the current is 2.16A and the power is 19.12W.
Summary
After testing, we found that it can do 9V PD charging for iPhone 12 and iPhone 12 Pro, whether using a 20W adapter or higher to 65W. And the power is around 20W. In different conditions, the charging power of the mobile phone will fluctuate from 1 to 2W. It is a regular performance.
