Broken electronic toys can be made useful, as shown in the following video. See how a broken toy can be repurposed as a battery pack. Pop a few rechargeable batteries into it and light up some LED’s. Domokun now has a spotlight!

Review of a 12V splitter. This is also called a 3-way cigarette lighter adapter .
This adapter plugs into a single 12V battery outlet and splits it into three outlets. Could be used to power three gadgets from your car or from wherever else you have a 12V outlet. I have one in my house for off-the-grid backup power.
