Samsung INR18650-30Q - The "pink" power all-rounder (3000 mAh)

The Samsung INR18650-30Q (recognisable by the distinctive pink-coloured cover) is one of the most popular 18650 batteries worldwide. It is considered the direct competitor to the LG HG2 ("Chocolate") and solves the classic dilemma between capacity and current. With 3000 mAh it offers a very high capacity, but at the same time delivers stable 15 amperes continuous current (and considerably more for short periods). This makes it the first choice for applications that require long runtimes and a lot of power.

Highlights at a glance

• Perfect balance: Usually you have to choose: High capacity (but low current) OR high current (but low capacity). The 30Q offers both: A lot of energy (3000 mAh) and enough power for almost all applications.
• High current output (15A+): Officially specified for 15 amperes continuous load. However, independent tests and practical use often show that it can safely deliver up to 20A (with temperature monitoring) as well. This is ideal for power-hungry devices.
• Stable voltage: The battery does not sag in voltage as quickly under load ("Low Voltage Sag"). This means your torch will stay brighter for longer or your e-bike motor will still pull strongly even uphill.
• Safe chemistry (INR): Uses safe nickel-manganese-cobalt chemistry. It is thermally stable and is less prone to "thermal runaway" on overloading than older ICR batteries.
• Versatile: The standard battery for e-cigarettes (vapers), high-performance torches, robot vacuum cleaners and cell replacement in Dyson battery packs.

The successor to the 25R

Many users ask themselves: Should I get the green 25R or the pink 30Q? The 30Q is essentially the upgrade. It offers about 20% more runtime at similar load capacity. Only if you operate the device at its very limit (permanently above 20 amperes) is the old 25R slightly more robust. For 95% of all users, the 30Q is the better choice today.

FAQs about the Samsung 30Q

Is this battery good for vapers (e-cigarettes)? 

Yes, one of the best. It is the standard for regulated battery holders up to approx. 45–50 watts per cell. It lasts noticeably longer than a pure high-current battery, but still delivers enough "punch".

Will it fit in my torch? 

If your torch accepts unprotected flat-top 18650s: Yes. It is excellent for torches such as the Emisar D4V2, Lumintop FW3A or bright Olight/Fenix/Nitecore models (as long as they do not require special batteries or button-tops), as it can power the turbo mode for a long period.

Can I use it as a replacement for my vacuum battery? 

Yes, the 30Q is very often used to re-cell Dyson battery packs (V6, V7, V8). It provides enough power for the vacuum motor and often increases the runtime compared to the original cells.

Are there counterfeits? 

Unfortunately yes, as the 30Q is very popular. Make sure you buy from trusted specialist dealers. Original Samsung cells have a lightly printed code under the shrink sleeve, which can be seen against the light.
