Capacity & Solar Input

This WOOJONG power bank stores 38800mAh in a Li-polymer cell, enough to recharge a smartphone 67 times or a tablet 34 times. Four fold-out solar panels harvest outdoor light to top up the pack, though charging speed varies with sun angle and intensity. The IP67-rated ABS+PC shell resists water, dust and flames for rugged outdoor use.

Use-case fit

It suits hikers, campers and travellers who need multi-day off-grid power for phones, tablets or headphones and value a built-in LED flashlight with SOS and strobe modes. Users who rely on rapid solar recharging in cloudy conditions or who require higher-wattage output for laptops should consider other solutions.

Deciding spec

The single figure that determines suitability is the 18W USB-C fast charge rate, which sets the maximum power delivery for both input and output across three simultaneous ports.

Questions about this item

How many full phone charges can the 38800mAh battery deliver before it needs recharging?

The 38800mAh cell is rated for about 67 smartphone charges or 34 tablet charges under typical use.

What happens to temperature and fan noise when the 18W USB-C port runs continuously?

The unit has no fan; heat stays low because the 18W output is modest and the flame-retardant ABS+PC shell dissipates warmth passively.

Which cables must I already own to charge three devices at once?

You need one USB-C cable and two USB-A cables to use the Type-C port and both USB-A ports simultaneously.
