Sovol SH03 dry box comes with 2 chambers controlled independently. You can only use one of them or make both 2 chambers working at the same time to heat up to different temperature for different type of filaments. Since SH03 can be sealed to store dried filaments without power, you can also make one chamber drying while another one for storage without power

Sovol SH03 equips with dual 200W PTC heater which can heat up to 85°C max temp faster and are more energy-efficient. SH03 dryer box can reach 50°C within 4 mins and reach 70°C within 12 mins. The dryer quickly heats with a built-in fan, circulating hot air 360° for uniform heating, effectively drying moisture filaments and improving your 3D printing results

No More Moisture in the Chamber:

When SH03 is working and the temperature inside the chamber reaches the preset target temperature, the moisture vent will open. Auto Dehumidification System helps moisture in the chamber quickly discharged and resolves the pain points of most filament drying boxes on the market for users

4 Spools Filament Dryer Box:

Each Sovol SH03 filament dryer is equipped with 4 filament holes which allow PTFE pipes through. The newly designed filament hole position is convenient for 3D printers with different extruder positions on the market. Large capacity of drying 4 spools of 1KG filament at the same time meets the needs of users to print with multicolor and use 4 printers at the same time, saving space and making the work area tidier

One Key Set for Each Type of Filaments:

Sovol SH03 has one-key temperature setting for 10 different types of 3D Printing filaments, including PLA, TPU, PETG, ABS, ASA, PVA, PET, PC, PA, PP.

Anyone know how this stacks up to the "gold standard" Space Pi X4?

I have been ISO a standalone dryer. I have a P2S w/ AMS 2 Pro. I would like the ability to dry out 4 spools while also printing. Wondering if its better to 'future proof' if I ever decide to print more than 4 colors at a time, and just get a second AMS 2 or just get something like this and maybe never use the drying on the AMS anymore.

You can look in to the Sunlu AMS Heater as an option which you have full control of independent of the printer or AMS. It was designed for the 1st gen AMS, but someone made a mod where you can use it on the AMS2 Pro: https://makerworld.com/en/models/...Id-2101253

I have it on a couple of my 1st gen AMS Units.

If I needed another dryer I'd probably pick up the one in this OP. I already have the Space PI X4, Polydryer, Sunlu S2 & a couple of the Sunlu AMS heaters. I had the S4 as well but when I got the Creality it made it redundant so I gave it to my nephew. Specwise, this SH03 seems to be able to do what the X4 can, namely heat up to 85 degrees and have independent heating in two chambers.
