Against the backdrop of accelerating global energy transition, the portable energy storage market is experiencing unprecedented high-speed growth. According to authoritative industry data, the global portable energy storage market is expected to reach RMB 88.2 billion in 2026, with a compound annual growth rate (CAGR) of 57% from 2020 to 2026. Global shipments broke through 28 million units in 2025, with a market size of approximately $14.5 billion, representing a year-over-year growth of 24.7%. In this booming market, VmaxPower (MULTIFIT), a leading new energy enterprise, has officially launched the M-PSSE series of portable power stations, covering three power models — 500W, 1000W, and 2000W — providing efficient, safe, and green energy solutions for homes, shops, outdoor activities, and emergency scenarios.
1. New Energy Market Experiences Explosive Growth
In recent years, the pace of global energy structure transition has continued to accelerate. The International Energy Agency (IEA) notes that solar photovoltaics has become the fastest-growing energy source worldwide, with global new PV installation capacity reaching an all-time high in 2025. Meanwhile, the increasing frequency of extreme weather events and challenges to traditional grid stability have driven a sharp rise in demand for backup power and off-grid power supply among residential and commercial users.
On the consumer side, the continued popularity of outdoor camping, road trips, and other leisure activities has also fueled the rapid expansion of the portable energy storage market. Data from iMedia Consulting shows that China's portable energy storage output value was RMB 55.74 billion in 2025 and is expected to climb to RMB 76.03 billion in 2026. Outdoor recreation is expected to account for 44% of application scenarios, with emergency preparedness at 37%, and application scenarios are becoming increasingly diversified.
2. M-PSSE Series: German Technology, Redefining Portable Energy Storage
The VmaxPower M-PSSE series portable power stations adopt German advanced technology, equipped with Grade A LiFePO4 (Lithium Iron Phosphate) cells, featuring high energy density, ultra-long cycle life, and high-efficiency charge-discharge capabilities. The series offers three models to meet different power needs:
M-PSSE 500W (1KWh)
Rated output 500W, equipped with a 27A MPPT solar controller, maximum PV input 300W. Battery capacity 314AH, cycle life ≥6,000 cycles (at 25°C, 100% DOD, 0.5P, @70% SOH), with a service life of 5 to 10 years. Weighing approximately 11.2KG with dimensions of 260mm x 320mm x 150mm, it is compact and portable, ideal for home backup, small shops, and outdoor camping.
M-PSSE 1000W (2KWh)
Rated output 1000W, equipped with a 45A MPPT solar controller, maximum PV input 500W. Battery capacity 314AH, cycle life ≥6,000 cycles. Weighing approximately 19.6KG with dimensions of 410mm x 330mm x 155mm, it meets the power needs of higher-power devices, suitable for home emergency, vehicle charging, and medium-sized outdoor scenarios.
M-PSSE 2000W (4KWh)
Rated output 2000W, equipped with a 66A MPPT solar controller, maximum PV input 1200W. Battery capacity 314AH, cycle life ≥6,000 cycles. Weighing approximately 26.3KG with dimensions of 550mm x 160mm x 410mm, it is the highest-power model in the series, capable of driving high-power appliances, suitable for full-home power, outdoor construction, and emergency rescue scenarios.
3. Core Technology Highlights
1. High Energy Density, Compact Size, Powerful Output
The M-PSSE series uses advanced materials and processes to store more electrical energy in a limited volume, meeting various household power demands. Charge-discharge efficiency ≥90%, supporting fast charging and providing stable discharge to ensure reliable power supply for all types of appliances.
2. Ultra-Long Cycle Life, 5-10 Years of Reliable Service
Grade A LiFePO4 cells with ≥6,000 cycles at 25°C, 100% DOD, the battery can reliably serve for 5 to 10 years, far exceeding the lifespan of traditional lead-acid and ternary lithium batteries, delivering lower total cost of ownership for users.
3. Multiple Safety Protections, Worry-Free Operation
Manufactured with eco-friendly materials and compliant production processes. Built-in multiple safety protections including AC input under-voltage protection, AC output over-current protection, PV input reverse polarity protection, PV input power limitation, battery overcharge/over-discharge protection, battery high/low temperature protection, over-temperature protection, and short-circuit protection, effectively preventing fires and electric leakage hazards.
4. Multi-Function Output, One Device for All Needs
The M-PSSE 500W features a 5-in-1 interface (inverter, MPPT solar controller, AC charger, DC 12V, USB charger), while the 1000W and 2000W models feature a 4-in-1 interface (inverter, MPPT solar controller, AC charger, USB charger), capable of powering multiple devices simultaneously for home, commercial, and office use.
4. Industry Standards Upgrade, Benefiting Compliant Enterprises
On April 3, 2026, the mandatory national standard "Safety Technical Specifications for Mobile Power Supplies" (GB 47372-2026) was officially released, taking effect on April 1, 2027. The new standard adds requirements such as battery nail penetration testing, lithium plating detection after cycle aging, intelligent management, unique coding, and over-voltage disablement, expected to eliminate approximately 70% of substandard capacity. VmaxPower M-PSSE series is designed and built to the highest safety standards from the outset, fully meeting or exceeding the new national standard requirements, positioning the company favorably in the industry consolidation.
Meanwhile, in June 2025, the Civil Aviation Administration mandated 3C certification for mobile power supplies, with the market share of compliant products rising from 50% to 89% year-over-year, and industry concentration continuing to increase. Leading brands with technological advantages and compliance capabilities will gain greater market space.
5. Looking Ahead: Green Energy Within Reach
QYResearch forecasts that global portable energy storage box sales will grow from $3.298 billion in 2024 to $21.05 billion by 2031, at a CAGR of 30.8% from 2025 to 2031. With the evolution of new materials such as solid-state batteries and sodium-ion batteries, and deeper integration of intelligence and IoT, portable energy storage products will advance toward higher energy density, smarter management, and broader application scenarios.
VmaxPower (MULTIFIT), as a pioneer in the solar clean energy sector, will continue to deepen its R&D in LiFePO4 energy storage technology, building on German quality standards to provide users worldwide with even higher-quality, more reliable portable power solutions, contributing to global energy transition and green low-carbon development.
