The Joyo Hot Plexi, model JF-32, is a compact distortion pedal from Joyo that simulates a classic amp rather than adding drive on top of one. Despite the name, Joyo describes it as simulating the classic JCM800 amp, "but with greater distortion and stronger output"1. In other words, it is aimed at the higher-gain Marshall-style sound, not the vintage Plexi its name suggests.
It is a small, light box: 118 mm long and weighing 200g, with a 1MΩ input impedance and 1KΩ output impedance1.
Power and bypass
The Hot Plexi runs on either a 6F22 9V battery or a DC 9V adapter, drawing 9mA1. That draw is low enough that a battery lasts a long time, and the pedal is easy to place on a powered board. Joyo states it uses a true bypass design, so your signal passes through untouched when the pedal is off1.
The name says Plexi, but Joyo's own description is a JCM800 simulation with greater distortion and stronger output. Players looking for a vintage low-gain Plexi sound should read the description, not the name1.
Where it sits among Joyo drive pedals
The Hot Plexi is one of several Joyo pedals built around amp-style sounds. Others in the range include the Joyo AC Tone, the Joyo California Sound, and overdrives such as the Joyo JF-01 Vintage Overdrive and the JOYO R-20 King of Kings. Where those lean toward cleaner or mid-gain territory, the Hot Plexi is the higher-gain, amp-simulation option in the lineup1.

Questions
Is the Joyo Hot Plexi true bypass?
Yes. Joyo states the JF-32 Hot Plexi uses a true bypass design, so the pedal passes your signal unaltered when it is switched off.
Does the Joyo Hot Plexi take a 9V battery?
Yes. Joyo lists the power options as a 6F22 9V battery or a DC 9V adapter, so it can run either way. Current draw is 9mA.
Is the Joyo Hot Plexi a Plexi or a JCM800 sound?
Despite the name, Joyo describes the Hot Plexi as simulating the classic JCM800 amp, but with greater distortion and stronger output. It is a higher-gain take on that amp sound rather than a vintage Plexi clone.
