Portable power stations are generally safe devices, but improper use can damage the battery, void your warranty, or create hazards. Here are the safety rules every owner should follow.

Charging Safety

Do Not Charge in Extreme Temperatures

Most LFP batteries charge safely between 32F and 113F (0C to 45C). Charging below freezing can permanently damage lithium cells. NMC batteries are even more sensitive to cold.

Rule: If it is below freezing outside, bring the station indoors before charging.

Do Not Leave Unattended During First Charge

The first charge is when manufacturing defects are most likely to surface. Stay nearby (not necessarily watching it) during the initial charge. If you notice unusual heat, swelling, or strange smells, disconnect immediately and contact the manufacturer.

Use the Included Charger

Third-party chargers may deliver incorrect voltage or amperage. Stick with the charger that came with your station or buy a manufacturer-approved replacement.

Storage Safety

Store at 50-80% Charge

Do not store your power station at 0% or 100% for extended periods. Both extremes stress the battery chemistry and reduce lifespan. Most manufacturers recommend storing at 50-80% charge.

Check Every 3 Months

Batteries self-discharge slowly over time. Check your stored station every 3 months and top it up to 50-80% if it has dropped below 30%.

Keep It Dry and Ventilated

Store in a dry location with airflow. Do not seal it in an airtight container. Do not store in direct sunlight or in a car during summer. The trunk of a car in summer can reach 150F+, which damages battery chemistry.

Usage Safety

Do Not Exceed the Output Rating

Running a device that draws more than your station's rated output trips the overload protection and shuts down the inverter. Repeated overloads can damage the inverter over time.

Watch for Extension Cord Hazards

Using thin or long extension cords with high-draw devices creates heat buildup and voltage drop. Use heavy-gauge, short extension cords (12 AWG or thicker for loads over 1,000W).

Ventilation During Use

Power stations generate heat during charging and discharging. Keep all ventilation ports unobstructed. Do not drape blankets, bags, or clothing over the unit. Do not operate inside a sealed tent.

Never Use Indoors With Gas Generators

Some people chain a gas generator with a power station for extended runtime. If you do this, the gas generator must be outdoors (carbon monoxide risk). The power station can be indoors.

What NOT to Do

Do not open the unit. There are no user-serviceable parts. Opening the case voids warranty and exposes high-voltage components.
Do not submerge it. Even IP65-rated units (like the Bluetti AC70) are splash-resistant, not waterproof.
Do not dispose in regular trash. Lithium batteries are hazardous waste. Recycle through an electronics recycling program or return to the manufacturer.
Do not fly with large stations. Airlines limit lithium batteries to 100Wh (carry-on only). Most power stations exceed this. Compact units under 100Wh (like some power banks) are the exception.

When to Contact the Manufacturer

The station will not charge or turn on after storage
You hear crackling, popping, or buzzing during use
The unit is hot to the touch (not warm, but painfully hot)
The battery percentage drops rapidly even with no load
Physical damage to the case, display, or ports

Most manufacturers offer 2-5 year warranties. Document any issues with photos and contact support promptly.
