18650 Lithium-Ion battery cells from GTF

For the also ordered Notebook Powerbank it must be 18650 flat head batteries. So without the increase at the positive pole.

For a 1/4 century, lithium-ion batteries were something special for me. Always made only especially for a notebook or a cell phone. Impossible to use in another notebook or another cell phone. Now for the first time I have Lithium-Ion batteries in front of me as very simple battery cells.

Just like once upon a time nickel cadmium batteries and later NIMh batteries.

For the Notebook Power Bank 12 are enough, in a Tesla-S there are 7,104.

New equipment 2021

Big differences in price and performance compared to previous items of my equipment. Meters, chargers and notebook powerbank.

Laptop powerbank
Can you really buy a 140 Wh powerbank for under 60 € that you can also charge with photovoltaics or in the car? Yes, I am very satisfied with this Laptop Powerbank.

Powerbank Accessories
Plugs for the car, universal power supply, photovoltaic, socket as in the car and a voltmeter are the most important accessories to the Notebook Powerbank.

Charger AA AAA NiMh 18650 Lithium Ion
Four completely different batteries can be charged at once by the Liitokala Lii 500. How many mAh have already been charged, the internal resistance and the voltage are displayed.

ASUS Plug
General power supplies, car adapters and notebook power banks come with a lot of different connectors, but unfortunately only the old ones and not the new ASUS connectors.

Wattmeter 230 V AC
A built-in rechargeable lithium battery stores the data when the meter is not plugged in. This Wattmeter costs under 10 €.

Wattmeter DC up to 100 A 60 V 6 kW
What is happening between the charger and the battery or between the battery and the load? As long as 100 A and 60 V are not exceeded, this under 10 € device provides information.

9 Volt block rechargeable via USB
Constantly be careful not to turn on the voltmeter for too long, NO THANKS! The 9 V disposable battery is replaced by a USB rechargeable 9 V lithium battery.
