Hetai Electronics (Jiangxi) Shines at 139th Canton Fair with Semi-Solid Battery Power Banks
Apr 21,2026
Hetai Electronics (Jiangxi) Co., Ltd. recently participated in the 139th Canton Fair in Guangzhou, showcasing its full range of cutting-edge power bank products and highlighting the latest advancements in portable energy storage .
At the fair, the company spotlighted its new power banks equipped with semi-solid state batteries. Compared to traditional lithium-ion batteries, these cells offer vastly improved safety—featuring superior thermal stability, puncture resistance, and longer cycle life—while boosting energy density by over 30%. The products fully support the QI 2.2 wireless charging standard, which raises the power limit from 15W to 22.5W, and integrates precise magnetic alignment and 40°C intelligent temperature control for enhanced efficiency and safety.
All models are certified under the new 3C (CCC) standard. Unlike the old version, the updated certification mandates stricter tests including a nail-penetration test and 135°C thermal abuse, elevating flame-retardant and thermal control requirements. The standard now ensures devices “do not ignite or explode” even under extreme abuse, marking a critical safety upgrade.
Hetai Electronics’ focus on safe, efficient, and innovative technology garnered strong attention from global buyers, further solidifying its leading position in the industry.
