This experiment is to compare both Anker Power Delivery and RavPower Power Delivery Portable Battery. Since 2015, I have fallen in love from Anker, I have brought so much Anker product since then, i.e. Lightning cable, micro USB cable, 10,000 mAh portable battery and charging hub. The problem is, I been struggling to charge some of my large device such as iPad and Laptop on the go, a Power Delivery needed for charging these. But a year before, there is nothing like that exist. In 2017 Anker announced a portable power delivery charging device, and this makes me very excited to get a hand on this product.
For evaluation on this product, I used a dummy USB manufactured by DROK, and drain the portable charger with different amp settings on DROK such as 0.5A, 1.0A, 1.5A, 2.0A, 2.5A and 3.0A; for further verification, I have used Muker-J7 to tested on iPhone charge count with each charge cycle. At the same time, I have also purchased a RavPower 26,800mAh Power Delivery portable charge for comparison.
