How Long to Charge a Mini Solar Generator (150 Wh)?

Charging a Mini Solar Generator (150 Wh) from empty to full takes about 3 h 32 min with its standard 60W charger. The battery holds roughly 150 Wh, and this page estimates the time for every common charger wattage, using the Lithium-ion (Li-ion / Li-Po) chemistry it actually uses.

Battery capacity: 150 Wh · Chemistry: li-ion

The Mini Solar Generator's li-ion chemistry thrives on regular, shallow discharge cycles—pulling it down to empty before recharging is actually the opposite of what you want to do. Unlike older battery types, lithium-ion prefers frequent top-ups throughout your day of field use. Whether you're powering your phone during a hiking trip or topping up a handheld radio at basecamp, letting this compact unit dip and recover throughout the day will preserve its longevity far better than draining it completely. The small form factor makes it tempting to squeeze every last bit of charge out before plugging in, but practicing restraint pays dividends in years of reliable service.

Since this power station lives in bags, pockets, and vehicle cubbies, storage conditions matter more than you might think. Lithium-ion chemistry is happiest when kept in cool, dry environments—ideally stored at a partial charge (around half capacity) during long periods of non-use. Before tucking your Mini Solar Generator away for winter or the off-season, give it a brief recharge every few months to maintain the delicate balance inside the cells; complete inactivity and heat are the enemies of battery health. This simple habit, paired with avoiding extreme temperatures and moisture, ensures your pocket-sized power companion is ready to deploy whenever adventure calls.

With the fastest charger listed here (12V car charging, 60W) it takes about 3 h 32 min. With the slowest (AC wall charging, 60W) it takes about 3 h 32 min. A pocketable power station sized for phones, lights and small radios.

Frequently asked questions

How long does it take to charge a Mini Solar Generator (150 Wh)?
From 0% to 100% with the standard 60W charger, it takes about 3 h 32 min. Using a faster charger shortens that; using a weaker one extends it, see the table above for exact numbers.
Why does my Mini Solar Generator feel warm during charging, and is that normal?
Yes, warmth during charging is a natural part of how li-ion batteries operate—the chemical reactions inside generate heat as energy is stored. Moderate warmth is not a concern, but if the unit becomes hot to the touch, unplug it immediately and let it cool in a well-ventilated space. Repeated excessive heat exposure can degrade the battery chemistry over time, so avoid charging in direct sunlight or sealed containers and ensure adequate airflow around the unit during recharge cycles.
Can I use solar panels to charge this device, and what should I know about real-world solar charging?
Solar charging is possible and perfect for extended outdoor trips, but be realistic about speed and efficiency—solar panels work best in bright midday sun and will charge much more slowly than wall power, especially through clouds or in shadowed locations. This generator's small size means solar charging can supplement daily use on camping trips rather than serve as your primary charging method. For reliable power replenishment, pair solar with traditional AC charging when you have access, and view solar as an emergency or supplemental option for true off-grid scenarios.
How is this charge time calculated?
We divide the energy needed (150 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.
