BC Master 10000mAh Power Bank REVIEW | MacSources

High-speed charging in a compact case.

I have a small obsession with power banks. I hate being left with a dead device — especially my phone. I think this feeling goes back to a time when I was stranded on the side of the road with my mom and brother with no way to communicate with my dad. It was the 1990s so cell phones were not a regular occurrence for people to have. We did have an old-fashioned car phone, but it ran off of the car battery and the car was dead. So, at this point in my life, I like to have a backup battery always on hand. I think that’s why I have a collection of them now. The newest addition to that collection is the 10000mAh Power Bank from BC Master. It’s a hard-working, slim battery that’s a good compliment for any mobile phone.


The 10000mAh Power Bank from BC Master is an 18W portable battery with power delivery as a feature. USB Power Delivery has the ability to negotiate power output over a USB Type-C connection to many different types of devices so that they safely receive a charge. The battery has three ports on it — Micro USB (Input), USB-A (Output), and USB-C (Input/Output). The unit is capable of Quick Charge 3.0 if the device can handle it. The battery is designed to be ultra-compact and scratch-resistant so that it can travel anywhere. With a capacity of 10,000mAh, the battery is capable of charging any iPhone 11 model, the iPad Air, or Samsung Galaxy devices. The power bank has built-in safeguards against overcharging, excessive current, and overheating. The package contains the power bank, USB-A to USB-C cable, and a user manual.

The power bank ships in a simple brown cardboard box. The front of the box has an outlined illustration of the product along with the brand name (BC Master) and the product name (10000mAh Power Bank with Power Delivery 3.0 and Qualcomm Quick Charge 3.0). The back of the box has the model number (BCBM-001) stamped on it in the top right-hand corner. Aside from that, there are contact details on the back. These details include a website address, but it doesn’t lead anywhere. The company does, however, have an active Facebook page.

Out of the box, the battery had a 50% charge. I used the opportunity to plug my iPhone 11 Pro into it and charge it up. The battery is just a little bit smaller in size than my iPhone and tucks away nicely behind it while the phone is connected with a short cable. I was very impressed with how quickly the iPhone recharged. When I started charging it the phone was sitting at 78%. After almost 50 minutes, the battery had gained 20% more power. The charging rate ended up being 0.42% battery life per minute. The power bank did not heat up at all and neither did the phone while it was charging.


As far as power banks go, this one from BC Master is a really nice option. It’s durable, charges devices quickly, and is easy to carry with you anywhere thanks to its slender figure. The power bank retails for around $25 (at the time of publishing) and is a good value at that price. I would recommend this to others looking for a solid option for chargers.
