Detailed overview: Zendure SuperMini 10000mAh 18W power bank
The Zendure SuperMini is a 10000mAh power bank that made its mark with its exceptionally compact format: barely larger than a credit card, it is about 30% smaller than a conventional 10000mAh battery. It is the power bank to carry everywhere, the one you don't feel in a pocket.
This feat is made possible by the use of high-density 21700 lithium cells, about 50% denser than the cells used in most power banks. Each cell offers 5000mAh, letting it concentrate 10000mAh in a small volume without compromising sturdiness.
For performance, it offers 18W fast charging over USB-C Power Delivery, complemented by a USB-A port, allowing two devices to charge at once. These 18W are enough to bring an iPhone to about 50% in 30 minutes. The SuperMini recharges itself in about 3 hours via its USB-C port. It also has an X-Charge mode particularly useful for low-power devices (smartwatches, wireless earbuds, bands), which many power banks fail to charge as they automatically cut the current.
Its fluted metal finish is elegant and sturdy. Its only limits stem from its purpose: at 18W, it is slightly behind more powerful recent power banks (30W and up), and its 10000mAh capacity corresponds to about two smartphone charges. Note that this classic model is no longer always easy to find in shops. But for an ultra-portable backup battery for daily or travel use, the Zendure SuperMini remains a benchmark for compactness.
Comparison
How does the Zendure SuperMini compare with compact 10000mAh power banks?
| Model | Capacity | Fast charge | Ports | Compactness |
|---|---|---|---|---|
| Zendure SuperMini | 10000mAh | 18W | USB-C + USB-A | Very high (credit card) |
| Anker PowerCore 10000 | 10000mAh | 12-20W | USB-C + USB-A | High |
| Xiaomi Power Bank 3 10000 | 10000mAh | 18W | USB-C + USB-A | Medium |
The Zendure SuperMini stands out above all for its record compactness, thanks to its high-density 21700 cells, where the Anker PowerCore and Xiaomi stay bulkier at equal capacity. Its 18W charging is average for its generation. For anyone seeking the easiest 10000mAh power bank to carry, the SuperMini keeps an edge.

Our tester's review: Guillaume Hoarau
The Zendure SuperMini made a name for itself by proving you could fit 10000mAh in a case barely bigger than a credit card. In use, that is exactly where its appeal lies: it slips into a jeans pocket or a small pouch without you feeling it, unlike the usual bulky bricks. Its 18W USB-C PD fast charging is enough to charge a smartphone to 50% in half an hour, and the USB-A port powers a second device. We also like the X-Charge mode, designed for small devices like smartwatches or earbuds, which many power banks fail to charge (auto cut-off). Its fluted metal finish is neat and gives a quality feel. The limits come from its format: 18W stays modest against recent power banks climbing to 30W or more, and 10000mAh is enough for about two phone charges, no more. But for a truly portable backup battery, the SuperMini remains a benchmark for compactness.
