Hobbywing HV 25A UBEC offers elegance, power, extended protection features, and simplicity all in a compact solution. Housed inside of an aluminum case, the UBEC is able to dissipate more head and reduce electromagnetic interference. A high efficiency DC-DC regulator paired with special designed circuitry offers conversion efficiency over 90%. Capable of 25A continuous current, the UBEC is the ideal choice for even the most demanding of applications.

The UBEC accepts a wide input voltage ranging from 3s 11.1V to 18s 66.6v, includes an external switch to power on and off the unit, and output voltage is adjustable from 5v, 6v, 7.4v, and 8.4v. UBEC shoot-through protection, which prevents the voltage of the main power supply from directly flowing to the output end of the UBEC and causing any damage to the connected electronic device when the UBEC is accidentally damaged, plus the protections like over-current, (output end) short-circuit, overheat, low-voltage cut-off guarantee safety and reliability.

Additionally, the UBEC features the ability to connect to a separate 2s LiPo providing backup in the event that the main power fails.

Great scale, an excellent buy
Color: Black&Silver
Is it possible to fall in love with a scale? I unboxed this one and, without reading any directions, put an empty 1/4 cup on it, turned the scale on, filled the 1/4 cup with coffee beans till I had the desired 17 or so grams, and turned the scale off. Easy-peasy! It’s small but sensitive, able to tell when a single bean has been added or removed. I almost didn’t get it because of the charging issue, but at least it tells you what the current charge is, and the way I use it I believe it will last several months without recharging. I’m so glad I bought this scale!

Simple yet easy must have for discerning coffee drinkers
Color: Black&Silver
I seem to never get the same results from my coffee machine and it varied even more with the new brand that we just bought. I now have to make more adjustments with the water temperature, based on age, type of beans, etc. That affects the amount of ground dispensed and consistency in the shot until I get a new batch dialed in. So the only way to regulate these changes is to weigh both the beans and water. Using this little scale has made things easier, less frustrating and more predictable. What’s awesome is that it will automatically begin the timer with the first drop and stop when the pressure remains constant. Simple yet easy and super convenient. If you are looking for a great little digital scale this should do the trick. Highly recommended.

Great Digital Scale!!
Color: Black&Silver
The Maestri House S2 scale has been clutch for dialing in my espresso shots. Memphis heat or not, this thing stays accurate and steady. The timer starts up quick, the readings are fast, and the compact size fits perfectly under my Breville without feeling cramped. It’s built solid, charges by USB‑C, and the precision really shows when you’re trying to get that perfect pull.

Has fit perfectly into my morning espresso
Color: Black&Silver
This seems to me to be an excellent small kitchen scale. I am new to the complexities of espresso making and have begun using this scale every morning to measure my dose and output. It is working just fine. Easy to operate, keep clean and store. I did not give it 5 stars because I have limited comparisons but I don’t expect and will not bother looking for anything better.

Perfectly fits what I needed for my espresso habit!
Color: Black&Silver
This Maestri House mini coffee scale is a great little tool for espresso and pour-over. The size is compact enough to fit under a portafilter or cup, and the 0.1g accuracy makes dialing in coffee much easier. I like the built-in timer, rechargeable USB-C battery, and clean black-and-silver look. It feels precise, practical, and easy to keep near the espresso machine. Great value for anyone who wants more consistent coffee.
