WUQ PB240B2 12/24V Lithium ion Battery Pack 35000mAh 129.5Wh

SKU CH-GRWY-Y82ZS

A rechargeable lithium-ion battery pack delivering 12 V, 24 V and 5 V outputs with 35000 mAh capacity and built-in protection circuits

  • Upholstery colorBlack LeatherSoft
  • Product typeSofas
  • 35000mAh capacity powers devices longer
  • 24V, 12V and 5V outputs run varied equipment
  • 5Wh energy rating supports extended use
  • DC 5521 and 4017 ports fit common connectors
  • Over-charge, over-discharge, over-voltage and short-circuit protection included

Power Output Options

This portable lithium-ion pack delivers three regulated voltages from a single unit. A 24V DC5521 port supplies up to 2.5A, a 12V DC4017 port provides a constant 12V at up to 2.5A, and a 5V USB port outputs up to 2.4A for phones or small accessories. The 35000mAh capacity at 3.7V stores 129.5Wh of energy for off-grid devices.

Thermal And Protection Behaviour

Built-in circuitry guards against over-charge, over-discharge, over-voltage, over-current and short circuits. If a connected load triggers protection, the pack shuts down automatically; reconnecting the included 29.4V 0.95A charger resets it without user intervention. No active cooling is mentioned, so the enclosure relies on passive dissipation during normal operation.

Sustained Load Characteristics

The 24V output voltage is not constant and will vary between 29.4V and 21V as the pack discharges, while the 12V rail holds steady. Maximum continuous draw is limited to 5A at 24V and 2.5A at 12V, so devices requiring higher steady current are not supported. Low-voltage equipment must not be plugged into the high-voltage port to avoid damage.

Questions about this item

How do I install the WUQ PB240B2 battery pack, and what step is often missed?

Turn the battery switch on before connecting the included 29.4V/0.95A charger to avoid an electric spark, then plug your device into the correct DC port — 5521 for 24V or 4017 for 12V.

What maintenance or replacement will the PB240B2 need later?

The lithium-ion cells are sealed and maintenance-free; if the pack stops delivering power after the protection circuit trips, reconnect the charger to reset it — no user-serviceable parts inside.

What limit appears first during sustained use of the PB240B2?

The 24V output drops as the cells discharge (29.4V down to 21V), while the 12V rail stays regulated at 12V up to its 2.5A limit, so voltage sag on the 24V side is the first constraint.
