Voltage Selectable Battery Adapters
For added convivence, there are voltage selectable battery adapters are available on the market. These units are helpful in situations where the device you are looking to power may be a temporary device, such as a holiday decorative device or if you have multiple devices you wish to power throughout the year, but not used all at ones.
For example, let’s say you have a set of string lights for Halloween which uses 2 AA batteries, and you have a Christmas Light-up Gnome which uses (4) AA batteries. You can use a voltage selectable battery to wall power converter and set the unit to the equivalent input power voltage, in accordance with the chart below.
The voltage selectable battery to plug – in wall adapter works by utilizing “dummy” batteries, as similar to the standard plug adapters already discussed. The selectable units come with a voltage setting switch and you’ll want to set the switch setting in accordance with the chart shown below. You’ll then utilize the appropriate number of dummy batteries and insert them into the battery compartments. Just like the standard wall plug converter, you’ll close the compartment and begin to enjoy the perks of not having to change batteries.
For Battery Voltage Selectable Adapters, follow the chart voltage selections below:
Number of Batteries | AA Total Voltage | AAA Total Voltage |
1 | 1.5V | 1.5V |
2 | 3.0V | 3.0V |
3 | 4.5V | 4.5V |
4 | 6.0V | 6.0V |
6 | 9.0V | 9.0V |
8 | 12.0V | 12.0V |
