Anker PowerCore+ Portable Charger

CONTEXT: I have now tested this charger at both a full charge, and at about the ~25% charge it arrived in. By testing, I mean comparing how it charged both my Galaxy S22 Ultra, and my Galaxy Tab S8+ , in comparison to my previous 20,000 mAh INIU portable charger.RESULTS: The findings were the same across the board. Using different wires, different ports on the portable chargers, different devices, different charge amounts on the ANKER and INIU battery, and even compared all these to a 25W wall charger & the included 60W wall charger. This $140 + charger performed worse when it came to charging my devices than my ~ $30 INIU charger.EXPLANATION: One at a time, I connected the individual battery to my device and wrote down the time my device determined it needed until a full charge (both devices being limited to the 85% battery health/care limit). In ALL CASES, the ANKER battery showed a longer charge time than the INIU battery did. Keep in mind, I changed & isolated all possible variables as stated above. The INIU battery has a maximum output of 22.5W, and showed SIGNIFICANT less time required to charge my devices than the supposed 45W ANKER battery.CONCLUSION: While the ANKER battery does have a higher maximum full charge (at 26,800 mAh vs 20,000 mAh), and also does charge faster (given it can take 60W input vs 22.5W input), when it came to what I valued most, that being charge time for my device, it failed horribly.I've very seldom every given negative reviews, but when it comes to a charger that I almost paid $150 for total, this was shockingly disappointing and am terribly satisfied. Let alone that a ~$30 portable charger was able to outperform the ANKER battery...I will hold off on returning the device for a few more days with hope to hear back on this and find out if I received a device that has a defect.
