Q1: Who are we?
Founded in 2009, we are a tech‑driven manufacturer with 200+ employees located in Guangdong, China. For over 17 years, we have been pushing the boundaries of portable power station efficiency and lithium battery pack safety. Our specialty is custom lithium battery products with advanced BMS and fast‑charging algorithms.

Q2: How do you guarantee quality?
Quality is built into every stage – from component sourcing to final assembly. We provide pre‑production samples for functional and safety checks, followed by a comprehensive final inspection covering insulation resistance, charge/discharge curves, and temperature rise. Our aging workshop runs each unit through 48‑hour stress tests to catch early failures.

Q3: What products do you offer?
We produce jump starters, solar generators, power banks, and a wide range of portable power stations (from 300W to 5000W). We also design custom lithium battery products for medical, marine, and telecom backup – including specialized voltage, capacity, and connector options.

Q4: Why choose you over other suppliers?
Because we combine 17+ years of deep R&D with in‑house mold and injection capabilities – we are not just an assembler. Our 200‑person team includes battery chemists and firmware engineers who can optimise your lithium battery pack for longer cycle life (≥2000 cycles for LiFePO₄) and higher peak power. We hold ISO9001 and multiple patents, and our Google‑trending features – like smart BMS, over‑current protection, and wide‑temperature operation – are what set us apart.

Q5: What services do you provide?
We support EXW, FAS, FCA delivery; accept USD, EUR, CNY; and offer T/T, L/C, D/P D/A, Credit Card payments. We provide full technical documentation, custom labelling, and multilingual support (English/Chinese). For custom lithium battery products, we also handle cell selection, PCM layout, and mechanical design.
