Bosch Professional GAA 18V-24 USB charging adapter 1600A00J61 1600A00J5W (WHL #49)

Something out of the ordinary for today, a brand new item, bought for disassembly and kind-of off-label use. A Bosch Professional USB charger which happens to have a 12V port also…

Contrary to my very first thought when I found this charger, it does NOT allow 18V batteries to be charged from USB or a 12V source. Maybe I should test that, but I doubt it. However, it does convert the other way – stick in a 18V power tool battery (ranging from 1.5Ah to 12Ah as of today) and get a USB charger with a lot of oomph, or a “heated jacked” power source with a lot of potential for baggy pockets.

24V to 5V 10A 50W DC DC Converter Regulator Car Step Down Reducer 24V to 5V 10AMP Daygreen CE Certificated (WHL #46)

Alright, part two of the DC-DC converter tests that’ll lead to a small project. This time we got a 5V/10A converter from Daygreen, model number B10-1224-05, shipped together with the 12V/10A unit from WHL #44. This item was 2.41€ excluding shipping, as described in that blog post.

It’s a brick style unit as well, a tad smaller, but also has two mounting holes left and right which are flush with the case. Contrary to the more powerful 12V one, this is only a plastic case that was potted, but it has four screw terminals and therefore offers more flexibility when it comes to attaching your own wiring.

Overengineered parts from China aren’t really my cup of tea, but this is for an upcoming project with power-hungry, rotating AND rusty plates, so I figured I would use something up for the task…

…and I don’t think I paid that much of a premium for it. So today’s item is a step-down converter model “D121” rated 10 amps at 12V, with 15-32V input voltage. Price was 2.86€ at the time; contrary to the usual item on this site, this was without shipping cost. […]
