Made in Mainland China.
Key Features
- Ultra-Long Battery Life: Up to 185 hours of operation using the interval (time-period) mode — the KС-certified 18650 lithium battery keeps air flowing far longer than standard corded pumps.
- Dual-Mode Operation: Switch between Continuous Mode for constant aeration and Interval Mode to extend battery life, plus three-speed adjustable airflow to suit different tank sizes and needs.
- Ultra-Silent Design: Triple noise-reduction technology — ABS sound-insulation shell, low-noise copper-coil motor with neoprene diaphragm, and suspended mute mounting — delivers a whisper-quiet experience.
- Power-Off Auto-Restart: When plugged in, the pump charges automatically and protects the battery. If the mains power cuts out, it instantly switches to battery power so your fish are never left without oxygen.
- Type-C USB Charging / Plug Dual-Purpose: Comes with a 1.2 m USB-C charging cable. Use it with a power bank, phone charger, or wall adapter — and it can run while charging.
- LED Digital Power Display: Real-time battery level readout lets you monitor remaining charge at a glance, so there are no unexpected shutdowns.
- Multi-Process Waterproof Protection: Block-glue compaction prevents moisture from reaching internal components. The flagship LD300 model achieves IP67 waterproof rating.
- Lightweight & Clip-Ready: Weighing just 196 g with a metal buckle clip, it attaches easily to a bucket, tank rim, or bag for portability.
- Smart AI Chip: Intelligent Algorithm 2.0 minimises power draw while maintaining consistent airflow output.

Important Usage Notes
- The pump can be used while charging via USB — no need to pause aeration during top-ups.
- On mains power failure, the pump auto-switches to battery and runs in Continuous Mode. Switch manually to Interval Mode to extend battery runtime.
- If the pump is briefly submerged in water, remove it, allow it to drain and dry, then resume use normally. Submerging beyond rated depth is not recommended.
- Power supply: AC 220–240V, 50/60 Hz (plug-in use); USB-C charging for battery use.
Why Aquarium Aeration Matters
Adequate dissolved oxygen is essential to the health of fish and other aquatic life. The U.S. Fish & Wildlife Service highlights that proper water quality, including oxygenation, is fundamental for the welfare of aquatic species. A reliable air pump helps maintain ideal conditions whether you're keeping pet fish at home or preserving live bait on a fishing outing.
Frequently Asked Questions
Q: Can I use this portable aquarium air pump while it is charging?
A: Yes! The USB lithium battery air pump supports charge-and-use simultaneously. Simply connect it to a USB power source via the included Type-C cable and it will run continuously, simultaneously topping up the internal battery for uninterrupted aeration.
Q: How quiet is this air pump for indoor aquarium or bedroom use?
A: The pump features three layers of noise reduction: an ABS sound-insulation outer shell, a copper-coil motor with a neoprene diaphragm, and suspended-mute internal mounting. Together these make it one of the quietest portable aquarium air pumps available — suitable for bedroom tanks and quiet office environments.
Q: Is this air pump suitable for outdoor fishing trips?
A: Absolutely. Its compact size (as small as 10×7.5×3.5 cm), lightweight build (~196 g), metal clip, and long-lasting lithium battery make it ideal for keeping live bait oxygenated in a bucket during fishing trips. No mains power is required — it runs fully on battery for up to 70+ hours depending on the model and mode selected.
Q: What is the difference between Continuous Mode and Interval Mode?
A: Continuous Mode runs the pump non-stop for maximum aeration — ideal for densely stocked tanks or larger volumes of water. Interval Mode alternates between active and rest cycles, significantly extending battery life (up to nearly double the runtime) — best for situations where you need long, unattended operation such as overnight or during outdoor trips.
Q: Which model should I choose — single hole or double hole?
A: Single-outlet models (S100A/S100B) are ideal for single fishbowls or small tanks and compact bait buckets. Dual-outlet models (S200A/S200B/LD300) can aerate two separate tanks or a larger tank with two airstones simultaneously, delivering 2×1.5 L/min or 2×2 L/min of airflow. The LD300 also adds IP67 waterproofing and a 6000 mAh battery for the longest runtime.
