Anker 733: Charging 3 Devices Simultaneously
The Anker 733’s three-port configuration (2× USB-C + 1× USB-A) makes it technically capable of charging three devices at once. But how well does it actually work?
Anker 733 Power Bank (GaNPrime 65W)
- 🔹 65W total output
- 🔹 10,000mAh + built-in plug
- 🔹 USB-C PD + USB-A ports
- 🔹 Charges a MacBook in 2 hrs
- ✅ All-in-one travel companion
- ✅ Built-in AC plug
- ✅ Fast 65W output
- ✅ Compact size
- ❌ No wireless charging
- ❌ Gets warm at full load
How Power Distributes Across 3 Ports
The Anker 733 has a 65W total power budget shared across all active ports. PowerIQ 4.0 manages this dynamically:
Default priority:
1. USB-C 1 (highest priority — up to 45W in 3-device mode)
2. USB-C 2 (medium priority — up to 18W)
3. USB-A (standard priority — up to 22.5W; shares budget with USB-C 2)
3-Device Charging Test Scenarios
Scenario 1: Laptop + Phone + Earbuds (Most Common Travel Setup)
| Port | Device | Power Delivered |
|---|---|---|
| USB-C 1 | MacBook Air 13 | ~35W |
| USB-C 2 | iPhone 15 | ~18W |
| USB-A | AirPods Pro | ~5W |
| Total | ~58W (within 65W budget) |
Result: MacBook charges at ~70% of native speed; iPhone at near-full speed; AirPods top up.
Scenario 2: Two Phones + Tablet
| Port | Device | Power Delivered |
|---|---|---|
| USB-C 1 | iPad Air | ~38W |
| USB-C 2 | Galaxy S24 | ~18W |
| USB-A | iPhone 15 | ~7.5W (via USB-A, QC 3.0) |
| Total | ~63.5W |
Result: iPad charges quickly, Galaxy S24 at near-native speed, iPhone slower via USB-A (use USB-C 2 for iPhone if speed matters more than tablet speed).
Scenario 3: Triple Smartphones (Best for Device Speed)
| Port | Device | Power Delivered |
|---|---|---|
| USB-C 1 | iPhone 15 Pro | ~27W |
| USB-C 2 | Galaxy S24 | ~18W |
| USB-A | OnePlus 12 | ~22.5W |
| Total | ~67.5W (slight dynamic throttle) |
All three smartphones charge at meaningful speed — none feel “abandoned.”
Practical Tips for 3-Device Charging
- Connect your most important device to USB-C 1 — it always gets priority
- Use USB-A for accessories (earbuds, watches, wearables) that don’t need speed
- Don’t connect a laptop + 2 phones expecting all 3 at full speed — the laptop will slow
- In battery mode (unplugged), add a slight speed reduction across all ports
