Digit DC021 Battery for Zong MF25 Cloud & Compatible Devices
A replacement DC021 battery for the Zong MF25 Cloud and its carrier-branded siblings.
This is a replacement for the internal battery inside the Zong MF25 Cloud pocket WiFi, and the same battery, model DC021, is also used in three carrier-rebranded siblings of the same underlying hardware: the Jazz 673 Cloud, Ufone MF683U, and Charji PTCL MF683. If one of those devices is running out of charge much faster than it used to, this restores it without replacing the whole hotspot. It is not a USB power bank for charging phones or other devices.

Digit DC021 Battery for Zong MF25 Cloud & Compatible Devices
PKR 800
A Zong MF25 Cloud (or its carrier-rebranded siblings) losing battery life
The Zong MF25 Cloud and its carrier-rebranded versions, the Jazz 673 Cloud, Ufone MF683U, and Charji PTCL MF683, all use the same removable DC021 battery. Like any lithium battery, it holds less charge after enough charge cycles, and a device that used to last a full day of portable use can drop to a couple of hours. If the device still connects and works fine when plugged into power, the battery is the far more likely cause than the hotspot's electronics.
Best For
- Owners of a Zong MF25 Cloud, Jazz 673 Cloud, Ufone MF683U, or Charji PTCL MF683 with reduced battery life
- Replacing a worn battery instead of buying a new pocket WiFi device
- Anyone comfortable opening their device to swap the internal battery
Not Ideal For
- Charging a phone or other device: this is an internal replacement part, not a USB power bank
- Any pocket WiFi outside the four listed compatible models: check your exact device model before ordering
- A device that will not power on even on wall power, which points to a fault beyond the battery

Questions About This Batteries
No. This is a replacement for the internal battery inside a Zong MF25 Cloud or its compatible siblings, fitting inside the device rather than charging other gadgets over USB.
