JD (京东京造) 35W Power Bank 20000mAh Review: Budget Built-in Cable Champion

On JD.com, the 京东京造 35W Power Bank has accumulated 1,000,000+ reviews with a stellar 99% positive rating. As JD.com’s own brand, it skips retail markups to deliver genuine 20000mAh capacity plus built-in cables at a price that rivals generic brands. Users consistently praise the accurate battery capacity, palm-sized design, and the convenience of built-in USB-C and Lightning cables. The main recurring feedback is that 35W shared output handles phones well but won’t fast-charge a laptop.

Priced at ¥89.9 ($12.50 USD) with a regular price of ¥99.9, this power bank undercuts most alternatives by 20-40% while including premium features like a digital display, 3C safety certification, and flight approval.

What Chinese Users Say

Value and Battery Accuracy

JD.com users overwhelmingly rate this power bank for its honest capacity and solid build.

JD’s own brand really delivers. The battery capacity is solid — much more consistent than other brands at similar prices. It has 3C certification and passes airport security without issues. The price is lower than competing brands while offering equal or better quality. — jiagangjun, JD.com verified purchase

This buyer highlights the trust factor of JD’s in-house brand. Unlike third-party sellers, JD directly controls manufacturing, which shows in the battery performance.

Bought this through JD’s same-day delivery — arrived by afternoon. It’s palm-sized and fits in a pocket. 20000mAh is genuinely useful. I charge my phone twice and still have juice left. The USB-C and Lightning cables are built-in, so I don’t carry extra cords. It charges both iPhone and Android without heat issues. The digital display shows exact remaining power. Under ¥100, I can’t find anything to complain about. — u*0, JD.com verified purchase**

Same-day JD logistics is a major perk in China. This user validates the dual-cable convenience and accurate battery indicator.

Portability and Design

This power bank is fantastic. It’s small and light enough to take everywhere. Charging speed is very fast — my phone goes from 20% to 80% in about 30 minutes. Battery holds charge well over multiple days. The packaging was nice, the price was great. Overall a perfect daily carry. — 茶*斯, JD.com verified purchase**

The compact 20000mAh form factor is a key differentiator. Many budget power banks at this capacity are bulky, but the JD model stays pocket-friendly.
