Yes. The 26,800mAh capacity is ideal for off-grid adventures. It can charge your phone 6 to 8 times and a tablet 2 to 3 times. Solar charging can top off the battery during daylight but should not be your primary charging method.

Yes. If your vehicle has a USB-C PD car charger (20W or higher), it can charge the bank in around 4 to 5 hours.

Yes. Place the power bank on soft towel during solar charging.

Yes, but thick cases may restrict wireless charging. Remove the case if the connection is loose or inconsistent.

No. The Solar Power Bank output is limited to 26W, which is insufficient for most CPAP machines that require sustained 30W to 60W output or more. Use the 300W Power Station instead.

With a 20W USB-C PD charger, the bank charges fully in 4 to 5 hours. Lower wattage chargers (e.g., 5W) may take over 10 hours.

The built-in solar panel provides up to 300 mA in full sunlight. Partial shade, cloud cover, or indirect sunlight can cause fluctuations. Reposition for optimal sun exposure and angle.

Yes. This model support pass-through charging.

Ensure you're using a USB-C PD-compatible cable. Also make sure to turn off Optimized Battery Charging. Restart device after turning off Optimized battery setting.

No. With a max 26W output, it cannot support most laptops, which typically require 30W to 100W input. It's designed for phones, tablets, cameras, and small electronics.

Yes. However, cold weather can reduce battery efficiency. Store the Solar Power Bank inside your coat or bag to keep it warm. Solar charging works in winter sunlight but at a slower rate.

The ProSeries Max cable is engineered for extreme performance and durability. It supports up to 240W USB-C Power Delivery (USB-PD 3.1), features an integrated E-Marker (EMCA) chip for safe high-power negotiation, and uses KEUTEK’s magnetic tip system to protect device ports from wear, dust, and accidental damage.

The ProSeries Max 240W cable is compatible with virtually all USB-C devices, including laptops, tablets, smartphones, gaming consoles, power banks, and portable power stations. It automatically negotiates the correct power level for each device, from low-power accessories to high-wattage laptops.

Yes. When paired with a compatible USB-C Power Delivery charger, the ProSeries Max cable enables fast charging up to 240W, allowing supported devices to charge at their maximum safe speed.

Yes. The built-in E-Marker chip ensures proper communication between your charger and device so voltage and current are negotiated safely. This prevents over-powering and helps protect both your device and charging equipment.

Yes. The ProSeries Max cable supports data transfer in addition to charging, making it suitable for syncing devices, connecting peripherals, and general USB-C data use. Data speeds depend on the connected devices and ports.

No. ProSeries Max magnetic tips are cable-specific and only work with ProSeries Max cables. They are not compatible with earlier ProSeries 60W or legacy KEUTEK magnetic cables.

Yes. The magnetic tip is designed to stay inserted in your device’s charging port. This helps protect the port from dust, debris, and wear caused by repeated plugging and unplugging.

The USB-C ProSeries Max (240W) cable is designed specifically for USB-C Power Delivery chargers and should be used with USB-C PD power sources for optimal performance. For USB-A chargers, KEUTEK offers a ProSeries Max USB-A (18W) cable designed for that use case.

Both ProSeries Max cable versions use the same ProSeries Max magnetic tips, allowing you to swap between USB-C and USB-A ProSeries Max cables without changing the tip in your device.

Only if the device supports USB-C PD and requires 60W or less. Many Ultrabooks are compatible.

Yes. It fits all standard 12V sockets. Some older vehicles may output unstable current to use high-quality cables for best results.

Ensure you're using the USB-C PD port and that the cable supports PD. Some cars may have lower voltage under load, reducing charge speed.

Yes, but to avoid draining your car battery, unplug when not in use -- especially if your outlet stays powered while the car is off.

Yes. The 100W panel is designed to work with the 300W power station, providing a full charge in 4 to 6 hours of direct sunlight.

Yes. These panels offer faster solar charging than the built-in panel on the power bank. Expect a full charge in 5 to 8 hours in good sun.

Yes. They are IPX4 splash-resistant and built for rugged use. However, they should not be fully submerged in water or left out in prolonged heavy rain.

Use direct sun only. Indirect light or windows reduce output significantly. Also, connect devices through the USB-A or USB-C ports with high-quality cables. If charging fails, try routing through a power bank.

Yes, but it won't charge in darkness. For safety, disconnect during rain, dew, or after sundown to avoid corrosion or reverse current.

Not directly. KEUTEK panels are designed for individual use. Combining panels requires voltage regulation and is not officially supported.

It's not recommended. While weather-resistant, battery-powered devices like the Solar Power Bank should be protected from freezing temps to avoid performance drops.

While output decreases in low sunlight, the KEUTEK 100W Solar Panel can still generate some charge. Clean off snow buildup and angle the panel toward the sun for best results.

Yes. However, cold weather can reduce battery efficiency. Store the Solar Power Bank inside your coat or bag to keep it warm. Solar charging works in winter sunlight but at a slower rate.

Yes. The AC outlet and USB-C PD port can charge most laptops and drones efficiently, depending on their power requirements.

Yes, as long as the fridge consumes less than 300W continuously. Startup surges must also stay under 600W.

Yes. Most CPAP machines run between 40 to 80W. With a 280Wh capacity, the station can power a CPAP for 3 to 6 hours, depending on settings.

Yes. Pass-through charging is supported, but performance may be reduced slightly due to heat buildup.

Yes. The power station can support LED TVs and electronics that draw less than 300W continuously and don't exceed 600W in surge power.

Yes. It uses a LiFePO4 battery and produces no emissions, noise, or fumes. It's safe for indoor use during outages or emergencies.

The system will shut off automatically to protect internal components. Disconnect the device, let the unit cool, and press the power button to reset.

Some electronics draw high surge wattage at startup. If the initial spike exceeds 600W, the station shuts down to protect itself.

Check that the panel is in full sunlight, MC4 connectors are properly attached, and the output voltage matches the input spec (12 to 26V, 100W max). Also, verify the polarity.

The LCD display will show 100% charge. The system automatically stops input to prevent overcharging.

Yes. The 100W panel is designed to work with the 300W power station, providing a full charge in 4 to 6 hours of direct sunlight.
