About Fast Charge

What is walkntalk Fast Charge?
Walkntalk Fast charge can charge your device up to 70% faster than standard 5W charging*. This means less time plugged waiting for your smartphone to reach 100% charged and more time getting on with what you want. If you need an urgent battery boost, a quick 10-minute charge with walkntalk fast charge combination might be all you need?


How does it Work?

The charging speed is measured by wattage which is calculated by the product of volt and ampere. In other words, the higher the wattage of the battery delivers, the faster it charges. Volts are a measure of voltage, amps are a measure of current, and watts are a measure of electrical power. A common analogy is a garden hose: Volts are equivalent to the water pressure in the hose; the current is equivalent to the flow rate; wattage is equivalent to the volume of the spout’s spray.
Standard charging technologies deliver typically 5V and 1.8A so around 9W or less. By comparison walkntalk Fast Charge Delivers 18W-36W depending on the charging source. This is significantly faster than standard charging speeds.

For it to work you require three things:

A Fast Charge (Power Delivery or Quick Charge) Compatible Device
A Fast Charge Cable (New connection types USB-C to Lightning or USB-C to USB-C)
A Fast Charge Power Source (Wall Charger, Car Charger or Powerbank)



    What are the most common types of Fast Charge?

    There are multiple charging protocols but the most common are Power Delivery and Quick Charge, they are similar but have some important difference to note.
    Quick charge is a proprietary technology which allows for the charging of battery powered devices, primarily mobile phones, at levels above and beyond the typical 5 volts and 2 amps which most USB standards allow for. To take advantage of Quick Charge, both the source providing power and the device must support it, meaning provided you have a Quick Charge charger and Quick Charger device an existing USB-A to USB-C you can charge faster using this protocol. This technology currently has a ceiling of 18W.

    Power Delivery

    Power Delivery (PD) is a charging protocol specification for handling higher power and allows a range of devices to charge quickly over a USB connection (important to note this is a USB-C connection) This standard was developed by the USB Implementers Forum. It operates by facilitating a conversation between two devices to negotiate a power contract so they can determine how much power can be pulled from the charger. Power Delivery starts at the 5V setting and is configurable up to 20V. Using a Fast Charge USB-C cable, it can handle up to 60W.
    Power Delivery allows for power to flow both ways, with no set direction based on circuit or connection. For example, if you were to connect two phones that support Power Delivery with a USB-C charging cable, one phone could charge the other and vice versa.

    Some advantages of PD

    In the future it will be able to deliver up to 100W (new cable type will be required) removing a few issues with charging larger devices using this protocol.
    This standard as aforementioned allows for compatible devices to share power and act as non-discretionary power sources.
    This technology will not overcharge your device but negotiate only the amount of charge as required by your device.
