Jump 1500W/2376Wh 220W Solar Generator

V-surging Technology refers to the technology exclusive to Vtoman which enables Jump 1500X to keep supplying power even when the connected appliances add up to a higher rated power than 1500W. (In V-surging status, the output power of Jump 1500X is stable at 1500W.) 

Jump1500X can power most devices, from cell phones, cameras, drones, refrigerators, blenders, to 85% high power professional tools, such as drills, cutters, hammers, etc. Jump1500x

Yes, all Vtoman power stations support pass-through charging. You can recharge your power stations and use them to charge other divices and appliances simultaneously.

First, you need to disconnect your Jump 1500X from the supported devices or apliances. Then you connect the extra battery to your Jump 1500Xand you can use Jump 1500X to power other devices and apliances again.

Compared to NCM battery, LFP battery is more stable and more resistant to high temperature. In pricking tests, LPF-battery power stations just slightly smoke when NCM-battery power stations are severely burning and even exploding.  

VTOMAN power station is not water-resistant. It is not recommended to expose it to rain. When your VTOMAN power station gets wet, if is is not inputing or outpputing, you can continue to use after drying it. The solar panels are IP65 water-resistant.

The conversiona rate of VTOMAN power station is greater than 85%, so you can estimate a rough period of time with 85% (at least) conversion rate. When the connected product power is lower than 1000W (rated power of your Jump 1000), the length of power supply = remained capacity of you Jump 1000 * 0.85 / product input power; when the connected product is beyond 1000W, the length of power supply = remained capacity of you Jump 1000 * 0.85 / 1000W. Please note that in the later case, although the product can be used, the effect may not be as good as that of its fully operating. In addition, refrigerators, microwave ovens, washing machines and other heavy-duty appliances may be more sensitive to the temperature, and their conversion energy loss does up when the temperature is higher. Neither such cases nor appliances with additional power output are subject to the formula mentioned above.

VTOMAN energy storage has a low current protection function. When the current is lower than 0.15A for more than 8 hours, VTOMAN power station will automatically stop operating to avoid abnormal power loss. Please note that when a refrigerator stops cooling, the current needed to support it may continue to be lower than 0.15A. In this case the power station may stop operation after 8 hours.

VTOMAN power station features ≤ 100uA self-discharge rate, which allows it to maintain 85%+ of is capacity after one year without being used. For the sake of safety, VTOMAN power station is usually charged to 60%-70% of its capacity when leaving the factory. After receiving your VTOMAN power station, it is recommended that you first open the AC output port to see if the internal fan rotates normally, and then charge the power station for 2~3 hours. It is also recommended you recharge your power station every 6 months when not frequently using it. 

VTOMAN portable power stations have jump start function. You can connect it with your car engine via the jump cable and start your car in seconds. (*Please note that jump cables are currently not included in the power station units.) For most of the time, any Vtoman power station with more than 5% of its battery can jump start a car. However, it is reconmmended you keep more than 10% of the battery to jump start your car with VTOMAN power stations.

No, you cannot. According to FAA regulations, any battery exceeding 100Wh is not allowed to be taken on a plane.  

When connected to an extra battery, Jump 1500X will display the average capacity of Jump 1500X and the connected extra battery on its LCD screen.
