USB Power Supply 5V,2A Including single Cable (USBPower)

USB Power Supply 2A - Incl Cable

Need a USB jack for charging or powering a project, but don't want to lug around a computer? This switching supply gives a clean regulated output at up to 2000mA! The adapter does include a USB A to micro B cable. This adapter is great for use with a project that require 5V DC. 

Will this power my Pi3B? Yes, depending on how many power hungry usb components you add.
This supply is however not a match to the official power supply in terms of supply, quality and longevity.
We strongly recommend that you invest in the official power supply.

How to calculate Support max LED Strip Length:
  1. Assumption: Your LED Strip has 60LEDs/m
  2. each LED 0.2W
  3. calculate max LED Strip Length: 0.2W/LED ×  60LEDs/m=12W/m
  4. 30W(this listing)÷12W/m=2m
  5. So this unit will support a LED Strip(60LEDs/m, 0.2W/LED) Length (Max)=2m lights

Hobbywing 5V 3A UBEC Step-Down Converter (Hobbywing power converter)

UBEC's (Universal Battery Eliminator Circuit's) are simply DC to DC step down voltage regulators! This UBEC is perfect for the Raspberry Pi, as it's able to take high voltages (5.5V up to 26V), and outputs a consistent safe voltage of 5V at up to 3A nominal or 5A max! The Hobbywing 5V 3A UBEC is a switch-mode type, which results in it being much more efficient than linear type UBEC's (so your batteries will last longer!)

UBEC's are perfect for applications where you plan to use the Raspberry Pi in a circuit with high voltages such as robots where you'll be driving motors!

Due to the voltage drop caused by the Raspberry Pi, it is recommended to input a minimum of 6.5V to receive a stable 5V output. Anything lower than 6.5V will result in a low voltage warning on the Pi.

Please Note. The Hobbywing UBEC can be set to output either 5V or 6V using an onboard jumper select! Please DOUBLE CHECK your output voltage is correct before connecting your microcontroller or circuit! 


  • Designed with an advanced switch mode DC-DC regulator IC.
  • Battery polarity reversal protection.
  • A metal shield covers almost all the electronic components, and a specially made filter is attached to the output wires to significantly reduce the electromagnetic interference.
  • The working status is shown by an indicator (LED), which lights when the output is in normal range.
  • Output Voltage: [email protected] or [email protected] (Changeable with an output-voltage select jumper)
  • Continuous output current: 3 Amps
  • Maximum output current: 5 Amps
  • Input: 5.5V - 26V (2 - 6 cells lithium battery pack or 5 - 18 cells NiMH /NiCd battery)
  • Size: 43mm*17mm*7mm (L*W*H)
  • Weight: 11g

SparkFun Hydra Power Cable (sparkfun)

The Hydra breaks out the 5V and GND lines from your USB power supply, computer or otherwise into three connectors: Barrel Plug, JST and alligator clips!

Behold, the Hydra! This USB power cable probably looks a lot like something you've hacked together before. We do it all the time, because what is a computer if not a 5V power supply that happens to run software?

The clips are shrouded to avoid shorts and the barrel plug is center positive. The cable is 6 feet long overall which give you plenty of room to work.

Remember that USB power does have its limitations. Most USB hosts will only provide between 100 and 500mA at 5VDC.
