PB2SL V2 – the return of a classic
Smarter. Safer. Better.
If you liked the PB2SL, you will love its new version.
We took everything users loved about the original PB2SL – and improved it. Faster charging, smarter display, enhanced protections, and smoother operation. This is the update you’ve been waiting for!
Easier to use
Starting
- Old version - You had to place the batteries first and then connect to power.
- New version - The order is arbitrary.
Low current charging mode
- Old version - You had to hold the button for a long time when the screen went dark. To exit this mode, you had to disconnect the device from USB.
- New version - A double click is enough to enter or exit this mode. The screen remains on to show the battery status.
Safer battery management
Battery replacement
- Old version - Replacing batteries while the power bank was in operation could damage the device.
- New version - You can safely replace batteries while the device is in operation.
Charging algorithm
- Old version - You had to disconnect the charger to exit fast charging mode; otherwise, a single battery would be charged with high current.
- New version - Charging a single battery is only at 5V. Fast charging is activated when a second battery is added and after they have been balanced beforehand.
Increased charging efficiency
Supported protocols
- Old version - Limited protocol compatibility only to QC3.0 and PD3.0.
- New version - Extended support for QC4+, AFC, SCP, PPS, and low-voltage direct charging protocols.
Output power
- Old version - Maximum 18W output.
- New version - Up to 22.5W output.
Fast charging support (input)
- Old version - Supported 9V and 12V.
- New version - Support limited to 9V only (safer charging with reduced heating effect).
More accurate readings
Displayed information
- Old version - Displayed the message „OUT1” after inserting a battery, even without a load connected.
- New version - Displays accurate battery information for each socket.
Refreshing battery information
- Old version - Refreshing was every 20s.
- New version - Refreshing occurs every 10s.
Screen timeout
- Old version - Timeout occurred after 35s on all channels
- New version - USB-C after 5s, USB-A after 38s
Wide compatibility, choose your capacity
Fits all sizes of batteries 18650, 18700, 20700, 21700. Possibility of self-modifying the power bank's capacity by replacing the batteries.

Fast charging
- PB2SL V2 supports multiple fast charging protocols, including QC4+, PD3.0, PPS, and AFC, providing efficient charging. It delivers an output power of up to 22.5 W, enabling fast charging of external devices.
- Connect with a QC3.0, PD 65 W, PD 45 W, or PD 20 W adapter to achieve maximum charging speed.


Two outputs:
USB-C and USB-A
Charge multiple devices simultaneously using the USB-C and USB-A ports for convenient multitasking.
Smart charging and discharging
A reliable solution for charging with 3 key functions.

Built-in balancer
This technology maximizes the lifespan and efficiency of batteries. Simultaneous safe charging or discharging of two batteries with different capacities.

Smart 3-stage charging
- TC Phase: cells discharged below 2.9V are 'woken up' with a lower current.
- CC Phase: after reaching 2.9V, the cell is charged with a constant current.
- CV Phase: when the cell is almost fully charged, the charger switches to charging with a decreasing current until reaching 4.2V on the cell. After reaching 4.2V, the charging process is complete - the battery is fully charged.

Reactivation of low voltage cells
Revive your excessively discharged batteries thanks to a special low current charging mode. Note! Not all Li-ion batteries can be saved with this special mode. For cells that have been excessively discharged for a long time, irreversible chemical processes may have occurred inside the battery.
Advanced protections
The charger / Power bank PB2SL V2 is equipped with a range of protections such as:
- intelligent detection of damaged batteries
- time protection
- overcurrent protection
- overcharging protection
- overvoltage protection
- short circuit protection
- reverse polarity detection
- so-called "soft start" - initial charging with low current
User-friendly design
