Powers in Sell Lemons are permanent ability unlocks that smooth out a run once the basic income ladder is already moving. Five of them are bought with Alien Investors, and two more are bought with Robux. They cover travel speed, remote management, fruit pickups, upgrade stacking, remote buying, time acceleration, and reset planning.
Quick answer: There are 7 powers. Manage, Run Faster, Stack Upgrade, Remote Buy, and Expert Picker are bought with Investors, while Speed Up Time (319 Robux) and Forever Purchase (599 Robux) are Robux unlocks. Investor powers reset on Evolution or Ascension; Robux powers do not.
How to unlock powers in Sell Lemons
Powers cost Alien Investors, so you first need to unlock the Rebirth system. Reach $77 Sextillion in cash and Joe the Alien will appear and turn on the Rebirth option. Rebirthing wipes your building progress but pays out Investors, and each Investor gives a 1% cash bonus. Freeing the Homeless Alien in the sewers adds another 1% cash multiplier on top.
Investor powers: costs, tiers, and effects
These five powers are paid for with Investors. Some have a single purchase, while others scale across multiple tiers that raise the multiplier as the cost climbs.
| Power | Cost (Investors) | Effect |
|---|---|---|
 Manage | 100 | Manage and upgrade every income source from one panel, so you stop walking back to each building. |
 Run Faster | 400 (x1.5) · 1 Billion (x2) · 1 Octillion (x3) · 1 Trevigintillion (x4) | Increases walk speed for faster travel between sources, phone offers, pickups, and new zones. |
 Stack Upgrade | 1,000 (+5) · 1 Trillion (+25) · 1 Decillion (+100) · 1 Vigintillion (Max) | Lets you stack multiple upgrades of one source at once instead of buying them one at a time. |
 Expert Picker | 250 (x2) · 1 Million (x4) · 1 Quintillion (x8) | Applies a cash multiplier to the fruit and money-bag pickups you grab around the map. |
 Remote Buy | 1 Trigintillion | Purchase income sources and upgrades remotely without visiting each building. |
Remote Buy sits at the very top of the cost curve at 1 Trigintillion Investors, which makes it a deep endgame convenience. Early and midgame players should not plan around it and should pour Investors into income sources, managers, upgrades, and reset multipliers first.
Robux powers: Speed Up Time and Forever Purchase
Two powers are paid products bought with Robux rather than Investors. The cash boosts below are also Robux purchases that hand you a chunk of profit instantly, which is useful context when you are weighing where Robux go.
| Power / Purchase | Cost | Effect |
|---|---|---|
| Speed Up Time | 319 Robux | Permanently doubles the income speed of everything, strongest when timers and managers already produce meaningful cash. |
| Forever Purchase | 599 Robux | Makes one selected upgrade permanent, so it keeps paying off through major resets. |
| Cash – 5 Minutes | 8 Robux | Instantly grants 5 minutes of profit. |
| Cash – 30 Minutes | 19 Robux | Instantly grants 30 minutes of profit. |
| Cash – 4 Hours | 39 Robux | Instantly grants 4 hours of profit. |
| Cash – 24 Hours | 59 Robux | Instantly grants 24 hours of profit. |
| Cash – 7 Days | 79 Robux | Instantly grants 7 days of profit. |
Note: Speed Up Time can interact with time-skip purchases, but the paid cash boosts are not themselves powers. They simply front-load income.
Which powers survive a reset
Reset behavior is the most important thing to understand before spending. Powers bought with Investors stay active through Rebirths, but they reset when you perform an Evolution or Ascension. Powers bought with Robux are exempt from those resets and stay unlocked no matter how far your progression tier moves.
This is why Forever Purchase carries the most weight for reset planning. A normal reset can wipe building progress while keeping long-term advantages like Investors. A convenience power only helps the current rebuild, but Forever Purchase locks in one upgrade that keeps helping every rebuild after it. Point it at something with lasting value, such as a strong global multiplier target, rather than the next button you can afford.
How to prioritize powers during a run
Treat powers as run helpers, not a strict checklist. The cleanest way to decide is to ask what is slowing you down right now and buy the matching power.
- Travel is the chore: Run Faster cuts the time spent moving between distant sources and new zones.
- Sources are spread out: Manage removes the walk-back loop by giving you one upgrade panel.
- You collect pickups while moving: Expert Picker raises what those fruit and money bags are worth.
- Repeated upgrades drive your income: Stack Upgrade compounds value by buying many at once.
- Timers and managers are earning well: Speed Up Time accelerates that output for good.
- Rebuilding the whole map is the main grind: Remote Buy is the deep endgame shortcut.
- Reset planning matters most: Forever Purchase preserves one key upgrade across reset loops.
Manage, Run Faster, and Expert Picker are the early-to-midgame friction fixers, so they pay off as soon as the map spreads out. Stack Upgrade and Speed Up Time matter once several systems are already multiplying. Remote Buy and Forever Purchase belong to the deepest progression, with Forever Purchase being the one to think hard about because a permanent upgrade reshapes every rebuild that follows.
