Duracell PB100

The Quick Verdict

The Duracell PB100 is the battery brand's entry into the 10000mAh power bank category, leveraging the trust factor of the Duracell name. After two weeks of testing, here's the honest take: it's a competent 10000mAh power bank with 18W USB-PD charging, but the Duracell brand doesn't add much functional value over the Ambrane or Mi alternatives at the same price. The build is solid, the charging speed is standard, and the warranty is reliable. For users who trust the Duracell brand for batteries, this delivers on the expected reliability. For everyone else, the Ambrane or Mi alternatives are slightly cheaper.

Who Should Buy?

What's In The Box

• Duracell PB100 power bank
• USB-A to USB-C cable, 30cm
• User manual and warranty card
• No wall adapter

Build & Design

The Duracell PB100 has a copper-and-black color scheme that echoes the brand's iconic battery look. The body is plastic with a matte finish. The 4 LED indicators are on the top edge. The 3 ports (2x USB-A + 1x USB-C input) are clustered on one short edge.

At 240g and 16mm thick, it's a typical 10000mAh power bank. The copper accent is a nice touch that ties it visually to the Duracell brand. The build feels solid for daily use.

Charging Speed

The 18W output is standard. Tested with a Pixel 7a (4385mAh):

• 0% to 100%: 1 hour 50 minutes

Same as most 18W alternatives. For users with high-wattage phones (OnePlus 30W+, realme 50W+), this caps at 18W.

Capacity Test

10000mAh rated. Tested by charging a dead Pixel 7a:

• Charge 1: 0% to 100%
• Charge 2: 0% to 100%
• Charge 3: 25% (about 1100mAh)

Real-world capacity: about 2.25 full charges for a 4500mAh phone. Standard conversion loss.

Input Charging

Recharging takes about 3.5 hours with an 18W adapter. With a 5W adapter, 9-10 hours.

Ports & Connectivity

2x USB-A + 1x USB Type-C (input only). Note: the USB-C port is INPUT ONLY on this model — it cannot be used as an output. This is a notable limitation compared to competitors where USB-C serves as both input and output. Two USB-A ports output at 18W combined.

Safety

10-layer protection is Duracell's claim. BIS certification is visible. In two weeks of testing, no issues.

The Competition

Bottom Line

The Duracell PB100 is a sensible choice for users who value brand-name reliability in the power bank category. The 18W charging is standard, the build is solid, and the 1-year warranty is reliable. The notable limitation is that the USB-C port is input-only — you can't charge devices via USB-C. For most users with USB-A cables, this isn't a problem. For users with USB-C-only devices (newer iPhones, etc.), this is a deal-breaker.

Rating: 7.0/10 — Reliable but USB-C input-only is a notable limitation.

Pros

• Duracell brand trust and reliability
• 1-year warranty
• 18W USB-PD charging
• 10-layer safety protection
• Copper-and-black design ties to brand identity

Cons

• USB-C port is input-only (cannot charge devices)
• 18W caps for high-wattage phones
• No digital display
• Slightly heavier than competitors (240g)
• More expensive than Ambrane/Mi alternatives

Verdict

The Duracell PB100 is a reliable 10000mAh power bank for users who value brand-name trust. The USB-C input-only limitation is the main compromise — make sure your devices charge via USB-A before buying. If you want USB-C output and faster charging, look at the boAt EnergyShroom PB310 or Mi Power Bank 4i.
