How Long Does the Anker 733 Take to Recharge Itself?
The Anker 733’s genius is that it can charge itself while plugged into a wall — its built-in prongs make it both a charger and a battery. But how long does refilling that 10,000mAh battery actually take?

Self-Recharging: The Key Mechanic
When you plug the Anker 733 into a wall outlet:
1. It provides charging power to any connected devices via its ports (65W total)
2. Simultaneously, it recharges its own 10,000mAh battery
3. The battery fills while the unit is plugged in — no separate cable needed
The self-recharge speed depends on how much of the 65W is going to connected devices.
Recharge Time: No Devices Connected
When plugged into a wall with nothing connected to output ports:
| Input Source |
Recharge Rate |
0→100% Time |
| Standard 65W outlet (built-in prongs) |
~30–35W to battery |
~3.5–4 hours |
| Plugged into another 65W USB-C charger |
~45–60W to battery |
~2–2.5 hours |
| Plugged into 20W USB-C charger |
~18–20W to battery |
~5–6 hours |
| Computer USB-A port |
~10W |
~10+ hours |
Recharge Time: While Charging a Phone (Pass-Through)
Pass-through charging — powering a phone while simultaneously recharging the bank — splits the 65W budget:
| Connected Device |
Power to Device |
Power to Battery |
Bank Recharge Time |
| No device |
0W |
~35W |
~3.5–4 hours |
| iPhone 15 |
~20W |
~15W |
~8–9 hours |
| Galaxy S24 |
~25W |
~10W |
~12+ hours |
| MacBook Air 13 |
~35W |
~5W |
~24+ hours |
Practical takeaway: When charging a laptop through the Anker 733, the battery refill is very slow. Best strategy: plug in at night with a single lightweight device connected — the battery will be full by morning.
Tips to Maximize Recharge Speed
- Leave output ports empty while plugged in overnight for fastest self-recharge
- Use the built-in prongs directly in the wall — this gives the highest input wattage
- Avoid computer USB ports for recharging — 10W trickle charge takes all day
- For a quick top-up: plug directly into wall for 1 hour = ~25–30% battery restored
