Do you leave your Chargers plugged in?

I unplug all chargers and also switch off the power strip. I don’t trust them, I also have no smoke alarm and sleep with plugs in my ears (help me get deeper sleep). I used to leave my Mac on but since the battery is dead now I also switch it off.

Thanks for the input!
This question is more about saving energy as a whole (1st world global scale) from all our walwarts as opposed to safety concerns.
Since my Xtar walwart has the green LED constantly ON I decided to unplug that one and only have it plugged in while in use.
I don’t how much it is actually using, maybe I need to get some type of walwart/plug checking device.

Buy yourself a plug in watt meter and check your chargers you will be amazed how much some will use in stand by.

I have everywhere switchable powerstrips which I always Switch off when not in use. Laptop, Chargers,TV, PC everywhere.

If you have 10devices which consume only half a Watt in standby you get
10*0.5*24*365=43kWh which are used for nothing….so doing that is very unecological and uneconomical.

Especially with the smart devices we have today which only consume very small amounts of energy it’s ridiculous.
For example if you use a phone with 10Wh and recharge it 365 times a year you would only consume 4kWh for using it one year. I choosed 10Wh because that is also the energy for recharging a18650.
so recharging a battery everyday consumes the same amount of energy like to let the charger stay plugged in but with the big difference that it has no use…

None of my chargers, adapters stay plugged in. I fear wear and rare.

I keep mine plugged into a power strip, and when not in use I switch off the power strip. I do this in the hopes that they will not be damaged by power surges or brownouts or whatnot.

Also some chargers (usually the less smart ones) used to want to be power cycled before inserting the batteries. I’m not sure if this is the case anymore.

I keep my RCA USB outputs and LaCrosse BC700 plugged in all the time but they are CSA approved items. Both have been tested and use less then 1 watt idling, and are on a powerbar that i can turn off when i want to.

I NEVER leave any direct from china items plugged in, they are typically not CSA, UL or CE approved and even if they have a sticker saying they are its more then possible they are counterfeit.


I use about 130 kw of electricity per month and don’t sweat the chargers much, but a surge protected power strip seems to be the right idea, and you can get ones with individual switches if you want.

I keep meaning to set up a charging station using a power strip with individual switches so that I can leave everything plugged in, yet have individual control, and separation from surges when not being used.

Best answer yet.

I resell dozens of flashlights each month (with cells and charger) and make each customer promise that they will not leave their chargers plugged in after use or leave them unattended while charging. Its good practice to unplug and takes so little effort, which might prevent your house from burning down and/or injuring someone.

Good discussion. What is a surge protected power strip?

Only one left plugged in is on USB charge from desktop. It's off when I shut down every nite and go to bed though.

However, I do leave Iphone charging over nite.

Since about four weeks ago, I always unplug or power off any chargers.

My brother lives on a grid where there are too many people connected with solar panels on their roofs. He had a Nitecore i4 plugged in but empty of batteries.
He and his wife were eating lunch one day, and they heard a loud “pop” in the next room. He investigated and smelled acrid electrical smoke.
His nitecore was dead!

A nice bright sunny day and with all those solar panels producing extra power, seems their grid voltage gets up over 255v when it should be ~240v.

His TV went out another day (a small power board fried) . His neighbours have reported similar issues with over-voltage in the area.

My son, on the other side of the country, has some gadget on his computer, modem etc that trips when voltage gets too high, and it records the time and over-voltage. This happens occasionally in the middle of hot sunny days here in Queensland. His analysis is that it is the over input to the grid by solar panels controlled by cheap Chinese controllers.

Keep ’em off when not in use, or protect them with something.

thats odd, bad design or something, solar power is low voltage D/C that has to be converted to A/C, so it should not be the panels but something wrong with the inverters.

Thanks, this is why i can’t see li ion flashlights becoming mainstream, the chargers are not there yet and the batteries need special care (some of mine are now overheating when i charge so i toss them, the chargers don’t have temperature protection, and non enthusiasts would just ignore it).
I wish 4AA was mainstream, eneloops are safe, chargers are plentiful, it could run XP-L chips at 3A without trouble, but would need temperature protection in the light, tailstanding at high amps, or the light in a blanket or drawer or duffel bag for example could cause big problems.

This country has switches on all (240V) powerpoints, so I leave chargers plugged in but flick the switch off.


laptop/phone chargers are always plugged in. 18650/etc chargers get unplugged mainly because I need use of that outlet.

We got the notebook chargers plugged in and connected to the notebooks all the time until I started reading about the cells. Now I turn the block with outlets they are connected to off in the evening and switch it back on as the first notebook is about to shut itself down because of low battery.

Cellphones I used to let them drain the battery and then recharge to full and kept the adapters plugged in. Now I recharge them when at 20-30% and unplug when 80-90 using 1 adapter for all the rest unplugged and not used anymore.

It is a version of this, with surge protection added.

Here is one with American plugs.

Phone chargers: IN

All others: OUT
