When choosing a portable solar panel, it is essential to match power and size to your specific needs. The VTOMAN VS400 is compared with similar alternatives from the same brand — the VTOMAN VS200, VTOMAN VS200 Pro, and VTOMAN VS110 — as well as the alternative Solar Panel FOSSiBOT SP400 Pro. All these devices share high conversion efficiency of up to 25%, IP67 water resistance, and compatibility with portable power stations. The main differences lie in output power, solar cell technology, and additional design features.
⚙️ The table below compares key specifications such as rated power, connector types, solar cell technology, and protection levels to highlight technical differences and their impact on real-world use.
| Parameter | VTOMAN VS400 | VTOMAN VS200 | VTOMAN VS200 Pro | VTOMAN VS110 | FOSSiBOT SP400 Pro | Practical significance |
|---|
| Power | 400W | 200W | 200W | 110W | 400W | The 400W models deliver twice the energy output but require more space than the 110–200W versions. |
| Efficiency | 25% | 25% | 25% | 25% | Up to 25% | All panels provide equally high energy generation density per surface area. |
| Cell type | Topcorn | Topcorn | Topcorn | Topcorn | Monocrystalline (bifacial) | Topcorn cells and FOSSiBOT bifacial design offer excellent light harvesting, with FOSSiBOT also capable of capturing reflected rear light. |
| Protection | IP67 | IP67 | IP67 | IP67 | IP67 | All panels are protected against dust and temporary water immersion, ensuring reliable outdoor use. |
| Connectors | MC-4, Anderson, XT60, XT90, DC5521 | MC-4, Anderson, XT60, XT90, DC5521 | MC-4, Anderson, XT60, XT90, DC5521 | Not specified | MC4 | VTOMAN provides a versatile set of universal plugs out of the box for various power stations. |
◎ The table below evaluates how well each model suits different usage scenarios and buyer profiles to help you choose the right option.
| Use case | Recommended product | Why |
|---|
| Off-grid power for large power stations in RVs or base camps | VTOMAN VS400 or Solar Panel FOSSiBOT SP400 Pro | Maximum 400W output quickly replenishes large energy reserves far from the grid. |
| Mobile hiking and camping with moderate power needs | VTOMAN VS110 | Lowest weight and compact dimensions while maintaining high efficiency for charging small devices. |
| General mid-length car trips and outdoor activities | VTOMAN VS200 or VTOMAN VS200 Pro | Optimal balance between strong generation performance and convenient transportability. |
The VTOMAN VS400 differs from lower-powered alternatives by offering twice the energy generation potential while maintaining a versatile connector kit and IP67 protection. It is best suited for users who require maximum charging speeds for large power stations in RVs or off-grid camps. If your power needs are more modest, the compact VTOMAN VS200, VTOMAN VS200 Pro, and VTOMAN VS110 will be much easier to transport.
