Recently, I showed you USB power adapters for cameras . These are particularly practical for video recordings, as they enable long shoots without changing batteries. With a USB adapter for tool batteries, you have even more power available for little money.

I have a whole range of Makita 18 volt cordless tools, such as this brilliant cordless hammer drill . Added to this are 5 batteries with 2, 3 and 5 Ah. Translated into watt-hours, this means 36, 54 and a whopping 90 Wh of mobile power. For comparison: a camera battery usually delivers between 7 and 15 Wh.
Makita offers two USB adapters for their tool batteries, the Makita DEBADP05 for the 18 volt series and the DEAADP06 for the 10.8 volt batteries. Both adapters are available for about 15 euros each, although the 18 volt variant fluctuates greatly in price.
The DEBADP05 has two USB outputs that are rated at 2.1 amps, as well as a power switch and a belt clip. In fact, the USB output of this model delivers a stable 2.5 amps without the voltage dropping too far. I tested this again with my UM25 USB tester and the electronic load (better to take the 35 watt model ) and get up to 2.7 amps before the output shuts off.
This allows not only cameras to be powered for a long time, but of course also smartphones and tablets to be charged, and on the terrace the battery provides long music entertainment with Amazon Echo and other USB Bluetooth speakers.
Of course, this is only worthwhile if you already have the corresponding tool batteries. These USB adapters are not only available for Makita batteries, but also for Bosch batteries and Einhell and others .
