Full interface classification of mains charger+portable power supply (outdoor energy storage/charging treasure)
It can be divided into six categories: AC interface, universal USB series, DC round port, high-power airplane model/energy storage interface, vehicle-mounted interface and Apple private interface. At the same time, it can distinguish four usage scenarios: charger input (plugging into the wall), charger output, portable power input (charging) and portable power output (discharging).
A, AC AC interface (mains/inverter high power)
1. Input plug of mains charger (plugged into household wall socket)
National standard two-pin flat plug (10A): small charger and adapter for mobile phones are standard.
National standard three-pin 10A/16A: original charger for high-power notebook power supply and outdoor power supply.
Pin suffix IEC C13/C14
C13: female port of adapter, computer host and outdoor power supply charging line; C14 is the male.
With high carrying power, 300W~2000W outdoor power charger is most commonly used.
Plum-tailed IEC C5: Portable Power Supply for Thin and Light Notebooks (within 65W)
2. AC output of portable power supply (inverter 220V to supply power to electrical appliances)
National standard five-hole socket: most outdoor energy storage power supplies come with pure sine wave output and are plugged into computers, rice cookers and projectors.
American standard/European standard socket: for overseas portable power supply.
Second, a full range of USB interfaces (mobile phone/digital universal, two-way fast charging)
1. USB-A (big mouth, old standard)
Appearance: rectangular single-sided insertion, no positive or negative.
Power: ordinary 5V1A/2A；; Fast charging supports QC18W and FCP22.5W
Scene: charger output, charging treasure/outdoor power output; Almost no input.
2. Micro-USB (Android old trapezoidal small mouth)
Single-sided plug-in, 5V basic charge, up to 18W fast charge.
Uses: old charging treasure, Bluetooth device, small adapter output; Now eliminated.
3. USB-C/Type-C (current mainstream universal interface)
Oval blind plug, 24 pins, supporting bidirectional power supply (both charging and discharging)
Protocol power:
PD3.0: up to 100W(20V5A)
PD3.1 EPR: up to 240W(48V5A), special for high-power notebook and high-end outdoor power supply.
Scene:
Output of mains charger: gallium nitride fast charging head for mobile phone and notebook.
Portable power input: PD two-way fast charging and recharging (65W/100W charging)
Portable power output: power supply for mobile phone, notebook and Switch.
4. Lightning (Apple Private)
Only the old Apple iPhone/iPad, the dedicated output of the mains power Apple charger, and only a small amount of portable power supply with this output port.
Three, DC round mouth (adapter/outdoor power high-power DC)
Structure: outer ring negative electrode, center needle positive electrode (few center negative electrodes are connected with reverse burning equipment), and the format is marked with outer diameter × inner diameter, with numerous specifications.
Mainstream model
5.5×2.1mm(DC5521): Routers, optical cats and small outdoor power supplies are the most common.
5.5×2.5mm(DC5525): medium and high power outdoor energy storage, notebook old power supply.
Small DC: 4.0 × 1.7, 3.5×1.35, 2.5×0.7, speaker, LED, small portable equipment.
usage scenario
Mains adapter output: original charger for notebook, router and outdoor power supply.
DC input of portable power supply: high-power mains fast charging (100W~800W), solar panel charging port.
DC output of portable power supply: 12V vehicle-mounted equipment, light strip and monitoring (12V/10A max. 120W).
4. High-power energy storage/high-current interface for airplane model (large-capacity outdoor power supply)
XT60/XT90 male and female
XT60: continuous 60 years, small energy storage and solar charging input.
XT90：90A High-current, high-power outdoor power supply with over 2000W fast charging input
Anderson interface
Industrial-grade high current, 40A/50A, high-end energy storage, special for RV power supply, supporting solar high-voltage charging.
Aviation plug: multi-channel charging for super-large outdoor power station and industrial portable power supply.
V. Vehicle-mounted dedicated interface
Cigarette lighter on-board male (12V)
City tram charging input: plug in the cigarette lighter of the car.
Portable power output: 12V10A, which supplies power to the car refrigerator and air pump.
On-board DC input port: Portable power supply can be plugged into the car to recharge power on the road.
Six, solar energy dedicated input interface (portable power supply outdoor recharge)
MC4 photovoltaic connector: high-power solar panels are standard, and outdoor energy storage is the mainstream solar input.
DC5521/XT60: Small folding solar panel, compatible with ordinary DC input.
Fast scene discrimination
