You plug the power bank in before bed and wonder whether it will be full by morning, or you plug your phone in at lunch and wonder how fast it fills. How long does portable charger take to charge depends on which side you mean: refilling the bank itself, or charging your phone from it, and the listings here give figures for both.

How Long Does Portable Charger Take to Charge
The quick answer is that a portable charger takes as long to refill as its input watts and capacity allow. The VRURC bank (on Amazon) lists a full recharge in about 6 hours, and the Anker 30W bank (on Amazon) takes power in at 20W. On the phone side, the Anker 30W bank brings an iPhone 16 Pro Max to 50% in 27 minutes, and the IAPOS 22.5W bank (on Amazon) brings a device to 60% in 30 minutes. A bigger capacity and lower input watts mean a longer refill, so a 60,000mAh bank takes longer than a 10,000mAh bank.
What sets the recharge time
The input watts set how fast the bank refills. The Anker 30W bank takes power in at 20W, and the VRURC bank takes it in at 5V/2.4A. The capacity sets how much there is to refill: a 10,000mAh bank refills sooner than a 60,000mAh bank on the same input. The wall charger matters too: a bank that takes 20W in needs a charger that gives 20W, or it refills at the charger rate. The cable matters as well: the Anker 30W bank has a 5.4-inch built-in USB-C cable, and the VRURC bank has 4 built-in cables, so the cable you use is the one in the bank.
| Bank | Capacity | Recharge and charge time | Amazon |
|---|---|---|---|
| Anker 30W | 10,000mAh | iPhone 16 Pro Max to 50% in 27 minutes; 20W input | |
| IAPOS 22.5W | 60,000mAh | Device to 60% in 30 minutes; up to 10 iPhone charges | |
| VRURC | 10,000mAh | Full recharge in about 6 hours; 5 outputs | |
| Anker PowerIQ | 10,000mAh | 5V/3A; 2 charges for iPhone 15 |
Use the table to match the bank to the time you need, and check the input watts before you buy.
How long to charge a phone from the bank
The output watts set how fast your phone fills. The Anker 30W bank brings an iPhone 16 Pro Max to 50% in 27 minutes, and the IAPOS bank brings a device to 60% in 30 minutes at 22.5W. The Anker 30W bank gives 2 full charges for an iPhone 15, 1.94 charges for a Samsung S24, 2 charges for an iPhone 14 Pro, and 10 charges for AirPods Pro 2, while the IAPOS bank gives up to 10 full charges for an iPhone. A bank with more charges lasts longer on a trip, but it also takes longer to refill.
Ways to refill a bank sooner
- Use a strong wall charger: match the wall charger to the input watts of the bank, so the bank refills at its own rate.
- Use the cable in the bank: the Anker 30W bank has a built-in USB-C cable, and the VRURC bank has 4 built-in cables, so you never hunt for a cable.
- Watch the display: the VRURC bank and the IAPOS bank show the exact percentage left, so you know when to recharge before heading out.
- Charge overnight: plug the bank in before bed, since a full recharge takes about 6 hours on the VRURC bank.
- Pick the capacity for the trip: a 10,000mAh bank refills sooner, while a 60,000mAh bank gives up to 10 iPhone charges for a long trip.
The gear: 4 power banks for the refill and the phone
The banks below cover both sides of the question: the refill time for the bank itself and the charging time for your phone, so the figures you worked out above map straight to a bank you can order.

FAQ: power away from the grid
How long does it take to fully charge a portable charger?
The VRURC bank lists a full recharge in about 6 hours. The time depends on the input watts and the capacity: a 10,000mAh bank refills sooner than a 60,000mAh bank on the same input.

The Anker 30W bank brings an iPhone 16 Pro Max to 50% in 27 minutes, and the IAPOS 22.5W bank brings a device to 60% in 30 minutes.
