Review: Very good, happy with the purchase. - I bought it because I'd forgotten back to Greece my multi-output Power Supply for my Guitars/Amps/Pedals gear set and I wanted a quick solution to be able, till my next trip to Greece and carrying back at UAE the aforementioned, to operate here in Dubai, one device only, either a Multi-Effect Pedal or a Looper, each time. Both, the Pedal and the Looper are working fine with the USB-DC Booster, I just had to purchase additionally a Reverse-Polarity Converter, to have the center/tip Negative. Wish they were manufacturing the same with more Outputs and Current capability. It would be a very convenient solution, as we all have dormant/not-in-use-anymore 5V Chargers from old abandoned Smartphones. I'm happy with the purchase and I ordered a 2nd one that is on its way already.
Review: one of the item does not have the led working - Ordered 2 quantities. Had to de-solder the connections as i needed center negative to se with guitar pedals. Though one of the item, the led voltage indicator does not work. Other than that, both worked as i intended for my use. Just need to take care of the units as they dont look durable enough to withstand accidentally stepping on them…

### ⭐ Didn't work with AZ-GTi telescope mount, disconnects intermittently
*by H***. on 6 February 2023*

I bought it to power 12V 0.75A telescope mount. It powered the mount well to start with, but kept getting disconnected intermittently. This happens on USB AC wall adapter and on USB QC power bank. The voltage indicator LED flashes momentarily while operating the telescope and the power goes off and the mount gets disconnected and all session settings are reset.
