40000mAh portable power bank

The WOOJONG power bank delivers a 40000mAh capacity for extended off-grid use. It suits campers, travellers and anyone preparing for prolonged outages. Three output ports charge a phone, tablet and headset at the same time. Dual Micro-USB and USB-C inputs let you replenish the bank with the cable you already carry.

Sustained output up to 22.5W

Under continuous load the unit maintains a 22.5W maximum through its USB-C port while the two USB-A ports share the remaining budget. The PD 4.0 and QC 4.0 chipset negotiates voltage steps without throttling during multi-device sessions. Heat stays manageable because the controller spreads current across all three outputs. Airline restrictions prohibit carrying this capacity on board.

40000mAh capacity decides suitability

This single figure determines whether the bank covers your whole trip or only a day. At 40000mAh it can recharge a modern phone several times but cannot be taken on commercial flights. Buyers who need a smaller, flight-legal unit should look elsewhere.

Questions about this item

How warm does the 22.5W USB-C output get when charging a phone all day?

The 22.5W USB-C port supports PD 4.0 and QC 4.0 fast-charging protocols. Higher power delivery can generate more heat during sustained use, so keep the power bank in a ventilated area rather than a sealed bag.

Which cables do I need to use the two inputs and three outputs?

The power bank has a two-way USB-C port and a Micro-USB input. You will need a USB-C cable for the USB-C input and outputs, plus a Micro-USB cable if you prefer to recharge via the Micro-USB port.

Can the 20W input recharge the 40000mAh capacity fast enough for daily camping trips?

The 20W USB-C input accepts PD 4.0 charging. Recharging the 40000mAh cell at 20W takes several hours, so plan to plug it in overnight or during long stops to have full capacity each morning.
