And finally, OnePlus's Warp charge can deliver up to 30W. Vivo's Dual-Engine Fast Charge can output 22.5W of power. Oppo's Super VOOC Flash charge can output 50W of power. All three versions output 18-20W of power.īut since the three manufacturers are spearheading the quick charge revolution, in 2018 they came up with even faster implementations so they introduced new names as well making things a bit more confusing for the inexperienced users. Oppo calls it VOOC Flash charge, Vivo calls it just Fast battery charging, while OnePlus used to call theirs Dash charge (now renamed to just OnePlus Fast Charge for legal reasons). Oppo, Vivo and OnePlus share some of their intellectual property and R&D and as a result, their phones use similar quick charging solutions. The current implementations in smartphones however only go as high as 18W of power output. The maximum power output is 100W because there are even laptops that rely on this standard for charging. It doesn't require proprietary hardware though it does require the use of USB-C to USB-C cable. USB Power Delivery is another quick charging standard and this one is not limited to a particular hardware manufacturer. Pump Express+ 2.0 is available as well as a more budget solution and it allows the use of a microUSB connector. The latest generation of the standard is PumpExpress 3.0 and it utilizes a USB-C connector for the charging cable. Similarly to Qualcomm, MediaTek has also introduced its own charging standard called Pump Express, which is supported by phones using the company's chipsets and it requires its own set of proprietary chargers.

Motorola is using this standard for its phones even though they are marketing it as TurboPower and QuickCharge is not mentioned anywhere. It is backward compatible with the previous generations and the most common implementations peak at 18W of power output. It's been through a few generations already with the latest one being QuickCharge 4+. Smartphones utilizing Qualcomm chipsets can make use of Qualcomm's QuickCharge protocol.

The real quick charging starts from there and up. The most common solution is the 5V/2A charging which delivers 10W of power and pretty much every phone other there supports this charging rate. Quick charging field is still very much fragmented and almost every manufacturer has its own solution - most of the time, including proprietary tech. With basic chargers outputting 5V/1A equalling to 5W of power, anything faster than that is considered quick or fast charging. This is why most benchmarks for charging speed (ours included) quote the battery charging level reached after a 30-minute charging session on an empty battery. An empty battery can be charged faster without any safety risk. The modern battery chargers adapt the charging parameters dynamically based on the level of charging the battery has reached. The charging protocol (how much voltage or current for how long, and what to do when charging is complete) depends on the size and type of the battery being charged.
