Description

The Speras PD2170 Power Bank Charger is a hybrid device combining the functionality of both a power bank and a battery charger. It supports 21700 and 18650 lithium‑ion cells, using parallel balance charge‑discharge technology so the device can also function as a power bank. You can charge two batteries at once, and each slot is controlled independently. The charger features LED indicators to clearly show the charging status and automatically detects the battery’s input voltage. With up to 90% power conversion efficiency, it uses a TC/CC/ICV three‑stage charging algorithm to preserve battery lifespan. It accurately cuts off at 4.2V when fully charged, and includes safety protections such as reverse polarity, short circuit, overcharge, and overheat protection. Built with flame‑resistant materials, it is both safe and rugged.

Features:

  • Dual independent charging slots

  • Parallel balance charge‑discharge tech allowing use as power bank

  • LED indication of charging status

  • Automatic input voltage detection

  • High conversion efficiency up to 90%

  • TC / CC / ICV three‑stage charging

  • Precise cutoff at 4.2V

  • Safety protections: reverse polarity, short circuit, overcharge, overheat

  • Constructed from flame‑resistant material
