Differences between laser power supply and battery
Battery Chargers or Power Adaptors are not necessarily the same thing. A power adaptor just transforms your mains voltage (240V or 110V depending on your country) to a suitable voltage for. So far I have talked about Voltage but the current power in terms Amp or Milliamps needs to be considered along with Voltage. Its all well and good having a 12V adaptor or power supply. Please note that making a purchase from following one of the links above may provide a small commission which helps in the running of this web site. Next thing to consider is the plug and polarity of that plug that inserts into the laser or device. Most these days are of the type pictured below,.
FAQs about Differences between laser power supply and battery
Can I use a rechargeable battery with a laser level?
Many laser levels are sold with rechargeable batteries together with chargers or power adaptors. Sometimes, users lose or misplace their chargers and might consider plugging in a charger for another device. There are risks involved in doing this as the image below highlights.
What kind of battery does a laser use?
The laser uses a rechargeable 3.7-volt 2500MAH lithium-ion battery. Since it's rechargeable, you don't have to worry about constantly replacing the batteries. You can just charge up the laser and leave it in the kit.
Are battery chargers and power adaptors the same thing?
Battery Chargers or Power Adaptors are not necessarily the same thing. A power adaptor just transforms your mains voltage (240V or 110V depending on your country) to a suitable voltage for the device, for example, 6V or 12V etc.
Can you plug a laser level into a Li-ion battery?
This is because there is no control over the flow of power into the battery. It could even cause a fire with Ni-MH or Li-ion batteries. So if in doubt do not plug it in, contact the supplier of the laser level for advice.
Can a DC power adaptor fit into a laser?
Even if it does fit into your laser it may have the wrong polarity. DC has a positive and negative terminal the same as your batteries. Some power adaptors and chargers have the positive terminal as the inner part of the plug and the negative as the outer. Some may be the opposite with the negative being the inner and positive being the outer.
Why can't I plug a DC battery into my laser?
Therefore, even if you have the correct voltage and current it may still not plug into your device. Even if it does fit into your laser it may have the wrong polarity. DC has a positive and negative terminal the same as your batteries.
