Test Methodology

All devices tested from 0% battery in both wall mode (plugged in) and battery mode (unplugged). Screen off, no background apps, ambient temperature 22°C. Each test repeated 3× and averaged.

iPhone Charging Results

iPhone Model Anker 733 Wall Mode Native Charger Difference
iPhone 15 (0→50%) 27 min 30 min (20W) +10% faster
iPhone 15 (0→100%) 87 min 95 min +9% faster
iPhone 15 Pro (0→50%) 25 min 28 min (27W) +11% faster
iPhone 15 Pro Max (0→100%) 95 min 100 min +5% faster

The Anker 733 matches or slightly exceeds Apple’s native 20W/27W charger speed — this is because PowerIQ 4.0 negotiates Apple Fast Charge protocol directly.

Samsung Galaxy Charging Results

Galaxy Model Anker 733 Wall Mode Native Charger Difference
Galaxy S24 (0→50%) 22 min 22 min (25W) Same
Galaxy S24 Ultra (0→50%) 18 min 17 min (45W) -6%
Galaxy S24+ (0→100%) 68 min 65 min (45W) -5%

For Samsung’s 45W Super Fast Charging 2.0, the Anker 733 delivers ~38–42W — close but not quite at maximum. Still substantially faster than typical travel chargers.

Battery Mode Speed (Unplugged)

Device Battery Mode (0→50%) Wall Mode (0→50%) Slowdown
iPhone 15 34 min 27 min +26%
Galaxy S24 28 min 22 min +27%
iPad Air 55 min 40 min +38%

Battery mode is slower than wall mode — expected, as the bank’s own battery is providing power rather than direct AC conversion. Still meaningfully faster than most travel power banks.

Multi-Device Simultaneous Charging

Setup Charge Rate (Wall Mode)
iPhone 15 + AirPods Pro iPhone: 25W, AirPods: 5W
Galaxy S24 + Apple Watch Galaxy: 35W, Watch: 5W
iPhone 15 + iPad Air iPhone: 20W, iPad: 40W
iPhone + Galaxy + AirPods All charge simultaneously at reduced rates
