Very good.
Ordered the 5Volt Version. As far as I can tell the board says 5Volt as well. But output is above 8 Volts. Fried one of my mp3 players because I trusted the product. So be very careful and check the voltages before use. Otherwise you'll be confronted with magic smoke coming out of your equipment. And to be perfectly clear I ORDERED 5 VOLTS. Not 9V but it does not deliver 9 volts anyway.
Received it today but there is no battery holder just the PCB. The pictures show there is a battery holder?
can be used on load upto 12 watts. not more than that. both battery and boards heats quickly
NOT AS SHOWN! Battery holders are missing! Otherwise, it does what it says.
Looks fine. Not yet testen.
okay👌
quality is good but have not received the holders
Quality ++
Today I received the product and found that there is no battery case as shown in the product sale photo. Please let me know. Thank you.
