To increase the Tank storage capacity of the Vacpack's slots in Slime Rancher 2, players must use the Fabricator to craft a particular Upgrade.

The Tank Booster is an Upgrade in the indie adventure sim Slime Rancher 2 used to increase the maximum storage capacity of Beatrix's Vacpack's slots. Technically speaking, the Vacpack does not have an "inventory" but instead possesses four slot-like Tanks that can carry a specific number of items. Every Tank can only carry the same item or creature. For example, if the first slot holds Hen Hen chickens, it is impossible to insert Pink Plorts into this Tank.

Item or creature specificity is not the only limitation of the Vacpack's Tanks. At the start of their adventure in Slime Rancher 2, players can only carry 20 of one thing at a time. If fans suck up 20 Pink Slimes, they can not carry any more, even if the rest of the Tank slots are free. Such a restriction might feel frustrating at first, but it does complement the simplicity of the game's "inventory management," allowing for no need for item organization. Unfortunately, the first limitation regarding categorized Tanks cannot be changed or improved. However, players can upgrade their Vacpack's Tank storage capacity by installing the Tank Booster Upgrade in Slime Rancher 2.

The Tank Booster in Slime Rancher 2 implements its storage advancements in intervals of tens, meaning that acquiring this Upgrade will increase the Vacpack's Tank capacity by ten each. After the first implementation, players will be able to hold 30 items or creatures per slot. With four slots, this improvement equals an increase from a total of 80 to 120, which is significantly substantial for foraging, exploration, and Conservatory management.

Accordingly, the Tank Booster Upgrade should be one of the main priorities during the early stages of one's adventure in Slime Rancher 2. To get this Upgrade, players must collect 450 Newbucks and 10 Tabby Plorts. Newbucks can be earned from firing Plorts into the Plort Marketplace depository near Beatrix's home at the Conservatory. Naturally, the Plorts of the starter Pink Slimes do not offer much profit, but the income gradually rises for Slime species, depending on their rarity.

The second required resource, Tabby Plorts, is acquired from Tabby Slimes, feline Slimes that roam the meadows to the west of the Rainbow Fields. Keep in mind that these Slimes only eat Meat like Hen Hens and Roosters. After collecting 10 Tabby Plorts, fire them into the Refinery beside the Fabricator to have the resources used for crafting. Enter the Fabricator's screen and unlock the Tank Booster Upgrade to increase Beatrix's inventory space in Slime Ranchers 2. Additionally, players might notice that there are two Upgrades left for the Tank Booster. These enhancements will likely require rarer resources and a single upgrade that can be found in Slime Rancher 2's hidden Treasure Pods or other areas that will be released in the future.
