About this product


  • Charge your 5V devices from any 1.8V+ source
  • Max output 1000mA
  • Can used with USB or 2pin 3.5mm spaced terminal blocks

Product overview

• Charge your 5V devices from any 1.8V+ source
• Max output 1000mA
• Can used with USB or 2pin 3.5mm spaced terminal blocks
• Low battery indicator below 3.2V
• Not suggested for 2A devices such as large screen tablets

Efficiently power or charge any USB 5V device using any power source 1.8V or using this boost converter. The USB connector must be soldered on, though you may use a 3.5mm spaced terminal block in place of the USB.

What power can I get from this?
The 2A internal switch allows you to get 500mA+ from 1.8V, 750mA+ from 2 NiMH, and 1000mA+ from 3.7V lithium-polymer and lithium-ion batteries or 3x NiMH/Alkalines. All of this is done while being boosted to 5.2V. It is boosted to 5.2V instead of 5V to compensate for USB cable resistance, but is safe to use with 5V devices. This boost converter is not advised for 2A devices such as large screen tablets.

Keep your project running
There is a low battery indicator that will let you know when the output drops below 3.2V. This boost converter will consume 5mA while active, and only 20uA while inactive.

Hi Maplin. Can you find out how long will it power my Pi for if I use a fully-charged 1000mAh Li-Ion battery please? I am using this for a console for my child. Thank you.
