Compact 20 000mAh Power Bank

The WOOJONG Zolo Power Bank stores 20 000mAh of capacity in a case that measures 4.72 × 2.89 × 7.24 and weighs 12.85 oz. It targets travellers and commuters who need several phone recharges without carrying extra cables. Two integrated USB-C cords, a USB-C port and a USB-A port let you top up four devices at once. The 2025 upgraded unit ships new with an 18-month warranty.

Integrated Cables Free Bag Space

Dual built-in USB-C cables fold into the body so you do not need to pack separate leads for a phone, tablet or laptop. A USB-C port and a USB-A port remain available for additional gear or for charging the bank itself. Four devices can draw power simultaneously from the combined outputs. Buyers who want more storage than 20 000mAh or who need a second power bank for longer trips will need a larger unit.

45W Peak Output Under Load

The bank delivers up to 45W from the USB-C port and up to 40W for iPhone 17 series handsets via the built-in cable or the USB-C port. Cables are rated for over 10 000 bends to maintain connection quality during repeated use. Sustained multi-device charging will share the total budget across ports so single-device peak rates drop when four loads are active.

Questions about this item

How many full phone charges can the 20 000mAh battery deliver before it needs recharging?

The 20 000mAh capacity provides roughly 4 full charges for an iPhone 16, so sustained use is limited by that total energy reserve.

Does the 45W output generate noticeable heat or fan noise during all-day charging sessions?

The unit has no fan and relies on passive cooling; it will warm up under continuous 45W loads but remains silent.

Which devices can be charged immediately using only the cables and ports already built into the power bank?

Two built-in USB-C cables, one USB-C port and one USB-A port let you charge up to four devices at once without carrying extra cords.
