How Long to Charge a Wireless Earbuds with Charging Case (10h Battery)?

Charging a Wireless Earbuds with Charging Case (10h Battery) from empty to full takes about 1 h 3 min with its standard 5W charger. The battery holds roughly 3.7 Wh, and this page estimates the time for every common charger wattage, using the Lithium-ion (Li-ion / Li-Po) chemistry it actually uses.

The charging case for your wireless earbuds is engineered to be your daily companion, bridging the gap between quick top-ups and extended listening marathons. Rather than viewing it as a standalone accessory, think of the case as an integral battery extension that seamlessly accumulates charge throughout your day—toss the earbuds back in whenever you finish a call, workout, or commute, and you'll find yourself with a fresh reservoir of power ready for your next activity. The lithium-ion cells that power both the earbuds and their case prefer frequent, shallow charging cycles over rare deep discharges, so there's no need to wait until the battery is critically low before returning them to the case.

Modern life rarely demands a full 10-hour stretch of uninterrupted audio from a single device, which makes this charging ecosystem particularly practical for real-world use. Most listeners find that casual daily habits—brief returns to the case between work sessions, overnight charging, or quick pocket resets—naturally keep the system topped up without requiring conscious battery management. For long-term longevity, store the case and earbuds in a cool, dry environment when not in use for extended periods, and avoid leaving them in hot vehicles or direct sunlight, as lithium-ion chemistry is sensitive to temperature extremes and benefits from moderate storage conditions.

With the fastest charger listed here (Fast charge charger, 18W) it takes about 17 min. With the slowest (Standard USB-C charger, 5W) it takes about 1 h 3 min. Compact true wireless earbuds with an integrated charging case that extends total playback time to 10 hours.

Frequently asked questions

How long does it take to charge a Wireless Earbuds with Charging Case (10h Battery)?
From 0% to 100% with the standard 5W charger, it takes about 1 h 3 min. Using a faster charger shortens that; using a weaker one extends it, see the table above for exact numbers.
How should I charge the case itself, and does it affect the earbuds' battery life?
Charge the case via its designated port using a standard power adapter; the case independently manages power delivery to your earbuds. The lithium-ion chemistry in both the earbuds and case work in harmony, so returning earbuds to a fully charged case is the most efficient way to maintain your overall playback reserve. Avoid letting the case fully deplete, as this can shorten the battery's service life over many charge cycles.
What's the best way to store these earbuds if I won't use them for weeks or months?
Place the earbuds inside the case and store both in a cool, stable environment—not in hot attics, freezing basements, or humid bathrooms. Lithium-ion cells perform best when kept at moderate temperatures and away from extreme conditions. If storing for a month or longer, ensure the case has some charge (roughly half-full is ideal) before placing it away, and check the charge level every few weeks if possible to prevent the battery from completely emptying.
How is this charge time calculated?
We divide the energy needed (3.7 Wh times the percentage you're charging) by the charger's effective power, which is the charger's wattage times the battery chemistry's real-world charging efficiency (85% for Lithium-ion (Li-ion / Li-Po)). The same formula powers both this page and our API.
