  • Delivers adjustable 4.3-27V DC output providing 5V 1.4A, 9V 0.8A or 12V 0.6A for low-power devices
  • Compact 33mm x 23mm board fits multimeter upgrades and portable instrument conversions
  • Supplied as 10-piece pack for multiple projects or spare modules

What this module does

This pack contains ten identical Type-C USB boards that combine a TP4056 lithium charger with a step-up converter. Makers and repairers can add a single 18650 cell to give low-voltage DC gear a USB-rechargeable power source.

Charging and output limits

The charger accepts 4.5 V to 8 V DC and delivers a maximum 1 A charge current at 4.2 V. The boost side supplies 5 V at 1.4 A, 9 V at 0.8 A or 12 V at 0.6 A, with a continuously adjustable range up to 27 V and a 2 A discharge ceiling.

Deciding specification

The board measures 33 mm by 23 mm and fits projects that need a compact 5 W charger with Type-C input and variable boost output. It will not suit designs requiring higher charge rates or fixed-voltage rails outside the 4.3 V to 27 V window.

Questions about this item

How do I choose between the 5 V, 9 V and 12 V output settings on these modules?

The board delivers 5 V at 1.4 A, 9 V at 0.8 A and 12 V at 0.6 A; select the voltage your device requires and stay within the matching current limit.

What does the 4.2 V charging voltage mean when I connect an 18650 cell?

Each module charges a 3.7 V lithium-ion cell up to 4.2 V at a maximum of 1 A, then stops automatically when the cell reaches full voltage.

What does the Type-C USB input actually support in practice?

The USB-C port accepts 4.5 V to 8 V DC from a charger or solar panel and feeds the TP4056 charger and boost converter; it does not negotiate USB Power Delivery.
