Lonely Binary XL6009 6-Pack Adjustable Boost Converter

Lonely Binary XL6009 boost converter modules are a six-pack for adjustable DC-DC step-up power projects. The listing specifies a 3.8V–32V input and 1.25V–35V adjustable output, with a multi-turn potentiometer for setting voltage. These ranges do not establish that every input and output combination is achievable, so match the module to your source and load requirements.

At a glance

Step-up conversion is intended to raise a lower input voltage to a higher output voltage.
A multi-turn potentiometer lets you adjust the output voltage.
Six modules suit projects that need several converters or spares.

What to know before buying

Listing details to confirm

The listing gives input and output ranges but no current or power rating, so confirm the module's capacity against the intended load. The stated ranges do not mean every input-to-output combination is supported. The 3.8V-32V range appears in the title and feature text, while product details list only 3.8 Volts as the input voltage. The item weight is listed as 90 Grams, with no per-module or pack basis stated. The listing also describes stable or reliable power without supplying performance measurements.

Who is it for?

A good fit for

DIY electronics and prototyping that need adjustable step-up voltage.
Arduino, Raspberry Pi, or ESP32 projects where the source voltage and load fit the module's confirmed operating limits.
Builders who can use several converter modules across multiple projects.

Less suited to

Projects requiring a specified current or power capacity, since neither is supplied here.
Applications that need a confirmed output above the available input voltage without first checking operating limits and load requirements.

The available aggregate rating is entirely five-star, but it represents only two ratings. That small sample offers little basis for judging reliability or voltage performance. For buyers, the missing current and power rating is more important to confirm for a particular load than the rating snapshot.

Frequently asked questions

What input and output ranges does the listing give?

It states a 3.8V-32V input range and an adjustable 1.25V-35V output range. These ranges do not guarantee every input and output pairing, and the listing does not state a current or power rating.

How is the output voltage adjusted?

The listing says a multi-turn potentiometer is used to adjust the output voltage.

How many modules are in the pack?

The title and product details identify a six-pack.
