FAQ'S AND SUPPORT

For RV and camper van use, portable power stations typically range from 1kWh to over 2800Wh. Smaller capacities are suitable for light daily use, while 1408Wh–2816Wh and higher are ideal for running refrigerators, cooking appliances, and multiple devices during extended off-grid travel or boondocking.

Carku heavy truck starting batteries support vehicle jump starting and parking air conditioning operation. Built with low-temperature LiFePO₄ cells, they deliver reliable performance in cold climates, offer over 3,000 charge cycles (up to 10 years of service life), and feature multi-layer safety protection. The battery also supports forced one-button start, GPS positioning, mobile app monitoring, and comes with a warranty included.

A portable power station for RVs can power essential appliances such as refrigerators, lights, fans, laptops, kitchen appliances, entertainment devices, and even high-demand equipment like microwaves or CPAP machines, depending on the power station’s capacity and AC output.

Most RV portable power stations support multiple charging methods, including AC wall outlets, 12V vehicle charging, and solar panel input. This flexible charging allows users to recharge while driving, at campsites, or completely off-grid using solar energy.

Yes. High-quality RV portable power stations use LiFePO4 battery technology combined with an intelligent BMS (Battery Management System). They offer long cycle life, thermal stability, silent operation, and produce no fumes or emissions, making them safe and reliable for long-term RV and camper van use.

While traditional lead-acid and AGM truck batteries typically last 3 to 5 years, a high-quality LiFePO4 truck starting battery can last 8 to 10 years or more under proper charging conditions. Its longer lifespan comes from a higher cycle life, better resistance to deep discharge, and reduced sulfation compared to lead-acid batteries.

For truck starting battery applications, Grade-A LiFePO₄ batteries offer higher safety, while lower-grade B or C cells carry a greater risk of failure.

Truck starting batteries using LiFePO4 technology can last over 3,000 charge-discharge cycles, providing significantly longer service life than conventional lead-acid batteries. With proper maintenance, they can reliably power your truck for over ten years.

The JS-557 auto emergency jump starter is a portable 12V battery jump starter you can carry anywhere. Typically, it takes about 30 seconds to 1 minute to jumpstart a 12V battery, depending on the battery’s condition and vehicle type. After connecting the jump starter, wait a few seconds before attempting to start the engine to ensure sufficient power delivery.

A: the 12V lithium-ion battery is built in CARKU jump starter. When your 12V car battery is nearly drained, you can take your jump starter out, plug one end of jump cable into the device, and other end to connect car battery "+" and "-", then start the engine. you can make it.  Besides, you can use USB cable to connect different output port to charge different mobile devices as a battery charger.

A: Choosing a portable jump starter is very important to your car and your safety. many accidents happen due to unqualified lithium battery built-in jump starter. so we should take those into consideration:

Power (Cranking and peak power decide whether jump starter can boost your vehicle.)

Safety (It is related to jump starter itself and your property and life.)

Multifunction (it will add more additional features to car jump starter, high value)

Brand (Good after-sales service if you buy the branded jump starter, such as CARKU)

Price ( we always choose the best price for best product)

A 1000W electric kettle used for 5 minutes per session needs at least 1000W continuous AC output and around 420Wh battery capacity (so a 500Wh+ unit works). This means a 5oowh+ portable power station can boil multiple kettles, charge devices, or run small appliances perfect for off-grid living, camping, or mobile use.

Yes — a 24V LiFePO₄ jump starter is widely considered one of the safest and most reliable lithium-based solutions for starting a 24V vehicle battery system, especially in heavy-duty or RV applications.

Carku heavy truck starting batteries feature a true 24V design for easy installation, certified safety (CE, FCC, RoHS, UN38.3), long service life of up to 10 years with a warranty included, reliable operation from –40°C to 60°C, smart power reserve to ensure engine starting, high-capacity energy for parking air conditioning, and mobile app support for real-time monitoring and control.

Under normal use, it can be recycled more than 1000 times.

If not in use, it can be stored for 6-12 months. However, in order to extend the service life, it is recommended to charge it every three months. If the lithium battery is not used for a long time, its performance will deteriorate and may affect the starting effect.
