Aren't you using a charger that has been unofficially customized? That is considered unregulated and the seller is also committing the same violation!

  • Product news

We are Earth Power Co., Ltd. Recently, robots and AGVs have been widely adopted and produced in Japan. Such robots and AGVs always require battery chargers, and we receive many inquiries about this at Earth Power. Q. Are there any battery chargers for unmanned transport vehicles that are safe to use and have obtained PSE certification? This is the question. Earth Power has also obtained PSE certification, so you can use our products without any issues. However, it seems that other manufacturers, in their attempt to produce at a low cost, have created products that do not meet the standards or lack after-sales service, leading to many problems. While it is understandable to prioritize "cost," it is important to note that the issues arising from focusing too much on cost can actually end up being more expensive. Regarding this issue, our battery chargers are shipped only as normal products, and we can provide certification documents. We also conduct warranty and repair analysis domestically. We have a wide range of products, so please visit our website for more details. Please note that this news may also have implications beyond just chargers.
