INIU's 22.5W 20000mAh portable charger is a compact high-capacity power bank that fast charges well and seems to hold close to its rated capacity. The battery life and broad fast charge protocol support stand out, and the price makes it appealing versus pricier updated models. The main tradeoffs are its weight for portability, the lack of listed safety certifications, and the built in cable design that turns some buyers away. A practical pick if you want capacity first and can live with a few compromises.

  • The power bank can hold a charge for months after purchase.

  • The charger supports almost every fast charge protocol tested on compatible devices.

  • The 20,000mAh model can be close to its rated capacity based on testing.

  • The product can be a practical option for powering scouts during a Jamboree trip.

    blcaes

  • The 20Ah capacity can make the power bank heavy for everyday portability.

    miotch

  • The listing may omit safety certifications for this specific model.

    sidewinder33625

  • The power bank can arrive dead-on-arrival, requiring replacement.

    PurpleSnake6860

  • The physical size may feel small for a rated 20,000mAh capacity.

Good deal on a good charger. Be aware 20Ah is pretty heavy for portability.

The 10Ah 45W charger that has hit front page a few times in the last month (for $11) is a better fit for my needs, personally.

I have one of these I bought on a previous deal. Holds a charge for months, supports almost every fast charge protocol there is (tested on my FNIRSI FRB58) and I didn't get quite 20000mAh on my ET5411 but it's close. Buying another.

The 45w version goes under $20 here and there. I have that one and love it. Would recommend waiting for that one if you're not desperate.

I cannot get this to show as anything other than 32.99 in cart, but also, None of the links go directly into a product page, it looks like a product rec page for the same described item

Thanks. I sort of passed on these due to built-in cables.
