Delivery 29 days. Everything is in working order. Brav for charging a toothbrush. I made a mistake with the connector at the output, it is the same in all of them (as on power supply units for routers 12), be careful who takes the 5 volt cord, it must be taken with an adapter.

Ordered on February 3, 2023, received by mail on March 6, 2023. in Kyiv. Well packed, no defect. Several orders were combined into one receipt. Thanks to the seller, I recommend!

Thanks for the delivery. I didn't use it in practice, so only four stars. Everything is well packed, whole, corresponds (visually) to the description Thanks Joom I recommend the product

Suitable for power supply of electronic blood pressure monitor. It has 4 batteries, I'm tired of buying it, and the special power supply is expensive.

I wanted the UF lamp to work from a power bank and ordered this cord, the lamp works only with a timer, but the light does not shine 🙁.

Everything works, it arrived quite quickly, I ordered several products, the seller sent everything together, which is very convenient)
