Can you charge a power bank with a fast charger?

Can you charge a power bank with a fast charger?

Yes, you can use a fast charger to charge your power bank. However, both your power bank and the charger you’re using must support fast charging technologies for this to work.

Is your power bank lacking quick charge capabilities? You can still charge it faster if the device supports higher power input, but this is not comparable to the charging speed offered by fast charging technologies. 

Charging technology compatibility

In general, for a fast charging technology to work between two devices, both must support it. This rule also applies to power banks’ fast charging; as a result, a power bank that lacks quick charging technology cannot be expected to charge rapidly when connected to a fast charge charger. So, before purchasing a charger with fast charging technology, ensure that your power bank is compatible with the charger’s technology.

All you have to do is look at the product’s listings on the website from where you purchased it, or put the brand and model into Google and then browse to the company’s website. You can also read the user manual that comes with the power bank.

There are several fast-charging technologies available today. The following is a list of charging technologies that major manufacturers have developed and integrated into their wall chargers and other devices:

  • Apple USB-PD and Google USB-PD (Power Delivery)
  • Qualcomm Quick Charge
  • Anker PowerIQ
  • Samsung Super Fast Charging and Adaptive Fast Charging
  • Motorola TurboPower
  • OnePlus Warp Charge and Oppo VOOC
  • Huawei SuperCharge

Simply put, fast charging occurs when the charger supplies more power to the gadget that is powered by batteries. In other words, increasing the charging current and voltage accelerates the charging process. The question that remains is whether these fast-charging methods are compatible with each other or not? While some charging methods are compatible with one or two other charging technologies, some are brand-specific.

Qualcomm Quick Charge

Although USB-PD technology is compatible with Quick Charge 4 and newer versions, Quick Charge 3.0 and previous versions will not work with anything other than Quick Charge-certified devices.

Samsung Super Fast Charging and Adaptive Fast Charging

Samsung’s Super Fast Charging and Adaptive Fast Charging technologies are compatible with Qualcomm’s Quick Charge and USB PD PPS-compatible accessories.

Motorola TurboPower

A TurboPower equipped device does not require a proprietary adapter to fast charge, similar to Samsung’s Adaptive Fast Charge. Instead, you can use any Quick Charge 3.0 adapter with Motorola’s charging standard. It is worth noting that there are three types of TurboPower adapters: TurboPower 15, 25, and 30.

OnePlus Warp Charge and Oppo VOOC

BBK Electronics, a Chinese multinational company, owns both OnePlus and OPPO. OnePlus licensed Oppo’s Warp Charge, formerly known as Dash Charge. This technology is based on Oppo’s VOOC (Voltage Open Multi-Step Constant-Current Charging) system. Additionally, Oppo developed significantly quicker Super VOOC charging technology. Unlike Quick Charge and Power Delivery, Oppo VOOC is a proprietary fast charging technology.

Warp Charge, like VOOC, is a proprietary technology that works exclusively with OnePlus phones, compatible wall adapters, and car chargers.

Huawei SuperCharge

Huawei’s Smart Charge protocol automatically switches between charging modes based on the plugged-in charging adapter and device, and as a result, it is USB-PD compatible. While purchasing a suitable wall adapter is required to take advantage of Huawei’s SuperCharge technology, native compatibility with Qualcomm’s Quick Charge standard means that any SuperCharge-compliant device can also benefit from Qualcomm’s Quick Charge.

Anker PowerIQ

Anker’s new processors enable the USB-C ports on its chargers and power banks to support Qualcomm Quick Charge 3.0 and Power Delivery up to 100W, allowing them to charge almost any USB-C device at the fastest possible speed.

Apple and Google USB-PD (Power Delivery)

USB Power Delivery (USB PD) is a relatively new fast charge standard that the USB Implementers Forum introduced, the creators of the USB standard.  Apple and Google both incorporated Power Delivery technology in their devices. They have, however, made modifications to the technology; for example, both companies use a different connector type. Unfortunately, other charging technologies are incompatible with Google Pixel and Apple devices.

However, Qualcomm has confirmed that its Quick Charge technology is compatible with USB PD PPS (programmable power supply).

Power output vs power input

A charger’s output is specified by amperage and voltage. The amperage (or current) represents the amount of electricity going from the battery to the connected device, whereas the voltage represents the strength of the electric current. Volts multiplied by amps equals watts, which is a unit of total power.

To improve the rate at which a device charges, most manufacturers either raise the amperage or adjust the voltage. However, rather than increasing amperage, the majority of rapid charging standards vary the voltage. 

The term “input” refers to the pace at which the power bank is recharged. Although the charger’s output power directly affects charging speed; nevertheless, the power bank’s input power should also accept the charger’s output power. 

If the charger used to charge the power bank offers less power than the power bank can handle, the recharge time will be longer than anticipated. However, this rule does not apply if you use a charger with a higher power output than the power bank’s required input. In this situation, the power bank and battery’s intelligent circuits will regulate the current to ensure that the power bank receives the specified amount. 

It’s worth noting that because the power bank has an intelligent circuit, using a charger with a higher power output than the power bank requires will not damage the power bank. However, if the power bank is from an unknown brand or is cheap and low-quality, the intelligent circuit may malfunction, resulting in the power bank getting damaged and causing a fire.

Can charging via a fast charger damage the power bank battery?

No. Due to the risks that come with batteries, particularly lithium batteries, manufacturers are constantly working to improve their safety. Because of these advances, batteries are now safe for fast charging, whether in smartphones or power banks.

Tips for charging your power bank faster

To charge your power banks as quickly as possible, follow the guidelines listed below.

Charge with a compatible charger and cable

In order to charge any gadget, in this topic a power bank, more quickly, it is required to use a charger that is compatible with the item. As previously noted, the charger must be compatible with the devices. When you use these chargers, you will be able to take advantage of the quick charging features that are built into each of these items. If you’re planning on purchasing the wall charger and charging cable separately, consider the following: In that case, you should also buy a cable that is capable of transmitting the power from the charger. Otherwise, you will not be able to take advantage of quick charging.

Avoid using low-quality and cheap charger and cable

Never use low-quality or cheap items, especially if they are counterfeit, because they almost never deliver the level of power that is stated on the product or packaging.

Don’t use pass-through charging

Pass-through charging refers to a power bank’s ability to be recharged while simultaneously charging the connected devices. While concurrently recharging a power bank and your devices may save time in the airport, you should be aware that the power bank’s recharge speed will be reduced.

Don’t charge in extreme temperatures

Lithium batteries are extremely temperature-sensitive, which affects their performance. As a result, always use your power bank and other battery-powered devices at operational temperatures to avoid damage and to maximize battery charging speed.

Use the high-power input port

Some power banks are provided with two or three input ports, depending on the model. Reading the user manual to figure out which one accepts the highest input and is also equipped with charging technology, then recharging the power bank with that one is the most efficient way to charge it quickly.

Use short cable

The length of the cable can affect the charging speed. While the difference may be subtle, it can have a negative effect on charging speed, especially if the cable is longer than 39inches.
