How Long HOPSTAR Takes to Charge
Most people treat charge time and run time as one and the same number. They're not, and the gap between them decides how you actually use the thing.
A short stretch on the cable, a couple of hours of use: here's what the HOPSTAR charge cycle looks like in practice, how the suction setting changes it, and where the spec sheet oversells the result.
The Short Answer
HOPSTAR charges from empty in roughly 90 minutes over USB, and a 30 minute partial charge is usually enough for one full session. Run time is a separate figure. At the lowest suction setting, expect about 120 minutes of continuous use. At the highest setting, expect closer to 60 minutes. If you charge the night before, charge time rarely matters. If you charge in a hurry, it matters a lot.
Charge Time and Run Time Are Different Numbers
The confusion is understandable. A device that charges in 90 minutes and runs for two hours looks efficient on paper, and the two figures are often printed side by side on the box.
But they're measured under different conditions. Charge time is measured with the cell empty, the device off, and a known power source. Run time is measured with the motor running, and the motor doesn't draw a constant current. Suction settings, pauses, and temperature all move the number.
That's why a quoted runtime is best read as a range, not a promise. HOPSTAR sits in the 60 to 120 minute band depending on how you use it.
Picture this: the first time you use HOPSTAR, you run it at the top setting for 40 minutes and assume the battery is weak. It isn't. The same cell would have run for nearly two hours at the low setting. Reading the setting alongside the runtime figure is the only way the number means anything.
What 90 Minutes on the Cable Buys
A full charge takes about 90 minutes, and the last 20 percent takes the longest. Lithium cells charge quickly up to about 80 percent and then slow down deliberately to protect the cell.
So 30 minutes on the cable gets you roughly 70 percent of a full charge. That's more than enough for a single session, and it's the figure worth remembering when you're short on time.
- 0 to 30 minutes. About 70 percent, good for one session.
- 30 to 60 minutes. About 90 percent, good for two sessions.
- 60 to 90 minutes. Full charge, and the final stretch is the slowest part.

Why the Suction Setting Changes Everything
Suction toys draw more power as intensity rises. On HOPSTAR the difference between the lowest and highest suction settings is wide enough to roughly halve the runtime.
At the low setting the motor runs a short duty cycle and runtime stretches past 100 minutes. At the top setting the motor works continuously and runtime falls toward 60 minutes. There's no single honest answer unless the setting is named.
Many people settle in the middle. Two or three of the mid settings cover the range most people use, and runtime there lands around 90 minutes.
A Charging Routine That Fits Real Life
By the time you've finished a session, the battery is rarely empty. HOPSTAR is small enough that one charge covers several days of light use, so a weekly routine is plenty.
Three habits keep the cell healthy:
- Charge before bed. The cycle finishes overnight and the device is ready the next evening.
- Avoid deep discharge. Topping up at 20 percent is kinder to the cell than running it to zero.
- Keep it at room temperature. A drawer works well. A hot car does not.
If you're travelling, a short 30 minute top-up is the single most useful habit of all. A small power bank covers two full charges, which is more than a week of ordinary use.
One more note on the spec sheet: runtime is measured with a fresh cell at room temperature, around 70 degrees. In a cold room the same cell delivers less, sometimes 15 percent less. That's normal for lithium chemistry, and it's another reason the quoted figure is a best case rather than a floor.

Where the Spec Sheet Oversells
The honest limitation is that the headline runtime is quoted at the lowest setting, and almost nobody uses only the lowest setting. The number on the box is real, but it sits at one end of the range.
A second limitation is charging speed. There's no fast-charge mode here, so a flat HOPSTAR takes 90 minutes regardless of the adapter you use. If waiting bothers you, this isn't for you.
Hold off if you want a device you can run for hours at maximum intensity without a break. The battery is sized for typical sessions, not marathons, and that's worth knowing before you buy.
Charge Once, Use Often
If a simple weekly routine suits you, these two are the place to start.
- Self-Love Ritual (3-Piece): one box with HOPSTAR, GODLIKE, and Velvet Touch lubricant. Best for anyone who'd rather spread three sessions across a week than pick a single tool.
- HOPSTAR: the rechargeable suction tool itself, where the low setting gives the longest runtime per charge.
