Promate has launched the world's thinnest 10000mAh power bank in India — the Acme-PD20 — offering an ultra-slim, lightweight design that is a genuine solution for travellers who struggle with bulky chargers. Available on Amazon and select offline stores at Rs 3,199, the Acme-PD20 comes with a two-year warranty and is pitched as the thinnest and lightest 10000mAh power bank ever made.
World's Thinnest 10000mAh Power Bank: Promate Acme-PD20 Specifications

| PD Output | 20W (USB Type-C) |
| QC Output | 22.5W (Qualcomm Quick Charge 3.0) |
| Input Port | USB Type-C |

Fast Charging and Safety Features
The Acme-PD20 is built around two fast-charging standards. Its 20W Power Delivery (PD) port via USB Type-C lets compatible smartphones and tablets charge at full speed, while the 22.5W Qualcomm Quick Charge 3.0 port handles a wide range of Android devices that support QC technology. Together, these two protocols ensure that nearly any modern device — whether it uses USB-C or a standard USB port — can charge quickly from a single unit.
Promate has also incorporated a dedicated protection layer inside the Acme-PD20 to guard against high-voltage spikes and overheating. This is particularly important when charging overnight or inside a bag. The power bank is compatible with any device that supports USB Type-A or USB Type-C charging, making it versatile enough to top up phones, earbuds, and smartwatches simultaneously.
Design: Premium Build in a Pocket-Friendly Size
Promate, the Taiwanese accessories brand, has focused on ergonomics with the Acme-PD20. The company claims the unit offers a better gripping surface and premium build quality despite its ultra-thin form factor. At just 5.8 cm x 7.9 cm, it slips easily into a jeans pocket or a small travel pouch — a clear advantage over conventional 10000mAh banks that tend to be noticeably thicker.
The power bank is available in two colour options — Black and Blue — giving buyers a choice to suit their style. Both variants share identical specifications and are priced the same at Rs 3,199.
Where to Buy
The Promate Acme-PD20 is available through Amazon India as well as various offline retail stores across the country. Both purchase channels come with the same two-year manufacturer warranty. For more accessories from this category, browse our brand listings.
Is the Promate Acme-PD20 Worth Buying?
At Rs 3,199, the Acme-PD20 sits in the mid-range segment for 10000mAh power banks, but its ultra-slim dimensions and dual fast-charging support — both PD 20W and QC 3.0 at 22.5W — make it a compelling option for frequent travellers and commuters. The two-year warranty adds extra reassurance, and the overheating and high-voltage protection make it suitable for everyday use. If portability and fast charging are your top priorities, the Promate Acme-PD20 is one of the more thoughtfully engineered options currently available in India.
