How long does the power bank take to fully charge?
Using PD fast charging, it takes about 3-4 hours to reach full capacity. Solar charging takes 8-10 hours in direct sunlight, while the hand crank provides emergency power at a rate of about 1% per minute of cranking.
How many times can it charge my phone?
With 20000mAh capacity, it can fully charge an iPhone 13/14/15 approximately 5-7 times, or a Samsung Galaxy S22 about 4-5 times. Actual results may vary depending on your device's battery capacity.
How long does it hold a charge when not in use?
The PowerGuard 20000 maintains up to 80% of its charge for 3-6 months when stored properly. We recommend recharging every 3 months for optimal battery health.
Will it work during extreme weather conditions?
Yes! It's designed to operate in temperatures from -4°F to 140°F (-20°C to 60°C). The rugged casing is water-resistant (IPX4 rated) and shock-resistant.
What happens if I leave it in the sun too long?
The PowerGuard 20000 features advanced temperature control and overcharge protection. It automatically stops charging when full, making it safe to leave in sunlight without risk of damage.

Be sure of your choice
Whether you're a parent who needs to stay connected with your children during emergencies, or you're a remote worker who can't afford to lose access to crucial online meetings, this matters to you.
And especially crucial if you live in areas prone to severe weather events, or if you're among the growing number of Americans working from home. It's vital if you're caring for elderly parents who might need emergency assistance at any moment, or if you're managing a team that relies on your availability.
