See the table below for more information on how mobile phone and tablets charging methods compare. Get Adapters for Charging (5 Volt - 1 Amp) in New Delhi, Delhi at best price by R.G. Providing less current will prevent charging or slow it down the same as a poorly designed charger can also prevent charging or slow it down. It doesn’t matter if the power supply / charger can provide more current then the device requires. ![]() This means it is important to match voltage between the charger and device. If the power supply can only supply 1 Amp then either the product will fail to work/charge or charge slowly as it can’t get enough current (or power) to charge the battery. If the power supply can supply more than 2.1 Amps this doesn’t matter as the product will only take 2.1 Amps. If a product requires 2.1 Amps then the power supply should be able to supply 2.1 Amps or more. It will try and take as much current as it needs. A product (e.g a phone or tablet) consumes current. Screw one corner of the LiPoly charger into one of the box’s internal PCB standoffs.Current is supplied by a power supply or charger. Carefully tuck everything inside the box. Assemble the 5-volt DC-to-DC step up PCB, polymer lithium ion battery, LiPoly charger, SPST switch, and hookup wiring per the SparkFun Electronics’ product datasheets.ĥ. These ventilation holes also enable you to “read” the LiPoly charger’s status indicator LED while recharging the battery.Ĥ. Finally, drill ventilation holes in the box lid. Drill two holes in the side of the box for enabling access for the external power wires (i.e., + & GND). Drill a 3/8-inch hole for the switch and install the switch. Remove the charger and cut a hole in the side of the box at this marked location.ģ. Temporarily install the LiPoly charger inside the project box. ![]() Remove the 5-volt barrel power connector from the LiPoly charger.Ģ. USB cable (SparkFun Electronics # $3.95)ġ.Gray ABS project box ( All Electronics #1551-KGY $2.10).SPST pushbutton ( All Electronics #PB-21 $1.35).LiPoly charger (SparkFun Electronics #PRT-00726 $16.95).100mAh polymer lithium ion battery (SparkFun Electronics #PRT-00731 $6.95).5-volt DC-to-DC step up PCB (SparkFun Electronics #PRT-08290 $9.95).Cost: $47.63 (excluding tax and shipping charges).Note: In the coming weeks, I’ll build a project that converts a 12-volt AVR Development Board into a 5-volt “candy bar” computer using this power supply. Add a pushbutton on-off switch and a USB rechargeable interface and you have a versatile power supply that can be slipped inside your pocket. The voltage output for this project is 5VDC, and a practical output that can be applied to a wide variety of digital components.Įven better, this power supply has a two-pin plug that can be quickly and easily snapped into a common two-pin header for a reliable and solid power connection. Sure power supply projects aren’t that sexy but they are, generally speaking, the foundation for every electronics project.
