A happy man.

I am always on the doing my inspections, at the same time doing home business. The purchase of the energy brick definitely helps with charging both my handphones while i'm on the move. While a low batt restrict me from taking photos with my handphone camera during my inspections, the fast charging from the energy brick ensures that i don't have to worry about that at all.

B20000 Carbon Fiber Energy Brick

Amazingly small and light for its function. Using it to extend my laptop battery life. If only have bigger battery capacity in small form factor. Although there is a limit for airline carry-on.

NB20000 Carbon Fiber Energy Brick (20,000mAh 3A 45W)

Able to charge all my device quickly, especially my Macbook Pro. Handy to bring it around when you’re out of office for work. However, may experience some intermittent stoppage during charging. I was charging my phone but it stopped when it reached 53%.


20000 mAH is more than sufficient to power various devices throughout the day. Excellent quality

MingShun Tan

Its more compact and convenience anywhere.

Good features but not as light as you’d think

The power bank is compact and dense. Build quality feels great. More than enough ports.

However it’s not as lightweight compared to other similar 20000 rated power banks. Meaning the difference in weight is not as obvious like the 10000 carbon version vs other 10000 power banks.

I observed that Nightcore packers frequently overlooked the items to pack.
