Description

A Fantastic Two In One Device!

XTAR PB2S takes the portable charger and battery bank all rolled into one. It supports 18650 unprotected/protected and 21700 unprotected batteries. The max length of supporting battery is around 73~74mm.
It is perfect as an outdoor camping and hiking power supply. So, it is also a good holiday or birthday gift for outdoorsmen.
The biggest highlight is you can pull your batteries from this unit into your daily carry flashlight or pull batteries from your flashlight to charge your phone in a pinch.
When going outdoors, the ability to carry only one battery bank/charger and multiple spare batteries is also a space saver.
XTAR PB2S beats all the other power banks because you can choose the best quality and capacity of batteries and can replace them as necessary, so it will have a longer lifespan. It also allows older cells to be used.

Features

• Power bank function
As a portable power bank, XTAR PB2S charges your phone, tablets, mods, or anything else you can use for USB for. PB2S can also charge "low-current" devices such as wireless headphones and USB lights.
• Fast charging
USB-C QC3.0+PD3.0 fast charging, compatible with most phones' fast-charging adapters on the market.
• Two Outputs
USB-C and USB-A ports can both be used for output and charge two external devices at the same time.
• Charging Safety
Intelligent detection and multiple protections ensure safety. High precision, auto cut-off when fully charged. Three-stage charging (TC-CC-CV) makes batteries healthier.
• DIY Mah Capacity
You decide the PB2S capacity. With two 21700 5000mAh batteries, it has the largest capacity of 10,000mAh. You can also use two 18650 3600mAh batteries to get a capacity of 7200mAh.
• Revive Over-Discharged Batteries
It can even bring a dead battery back to life (this over-discharged battery must have a voltage above 1.3V or 1.4V).
• Readable Display
The display is clean and easy to read, with shown internal battery charge, amps output, and voltage.
• Magnetic Cover
The magnetic lid covers your removable batteries, dust-proof and drop-proof. Built-in ribbon, easy for removing the batteries.
• Rubberized skin, along with the robust build quality and feel.
