This Anker 20,000mAh power bank is best understood as a basic, high capacity backup for normal speed phone charging and low drain gear. The 15W output can still fit many phones that top out around 25W to 27W, and it is handy for overnight charging of flashlights, headlamps, and GPS units. The digital gauge is a useful extra. The main drawbacks are the slow 15W charging, the multi hour recharge time, and the missing Wh and weight specs. At $26.99, the value feels better only if fast charging is not a priority.

  • The power bank can work well for normal-speed charging when higher capacity matters more than fast charging.

  • The 15W output may match some phones' maximum charging rates, such as Galaxy S24 models.

  • The deal may be improved by an optional 10% coupon, which can improve overall value.

  • The power bank can be useful for phone charging when PPS support limits higher wattage on Samsung and Pixel devices.

  • The listing does not provide Wh capacity or weight details, which makes it harder to judge the battery and portability.

  • The 15W charging speed can feel very slow in practice, especially for a 20,000mAh power bank.

  • Recharging the power bank itself can take multiple hours, including around 4-5 hours.

  • The 15W output may not be sufficient for reliable backup power needs beyond phone charging.

Is there a competition for who can make the world's slowest power bank? Or did they find a 10 year old case of these in the back of the warehouse?

Somehow the specs never state the Wh capacity (because you cannot play that number). Nor the weight.

Anker needs to chill out with their prices ASAP, they're about to be phased out by Iniu and Baseus at this point.
Actually saw a tear down video or article somewhere showing INIU using better internals and having closer real power storage and speeds compared to the advertised than Anker.
šŸ¤” I'm questioning the deal score here that got this the front page...

This isn't for fast charging, but it still has a lot of good use cases because it is great for normal speed charging where you need a larger power bank than the average 10,000mAh one, so thats why I bought it because I wanted high capacity but charge speed isn't important for my needs because I'm just plugging my camping flashlights, headband light, and GPS unit into it at night so they are fully charged the next morning.

I would just rather buy a 20000 mah power bank from a reputable brand for just $5 more. It's always better to have the capability to charge fast.

Yea this is very slow for such a huge powerbank. Takes forever to charge. There are faster charging (30/45W) Anker 20ks that go on sale for this price range occasionally

All Anker products are always pushed to the front, and people are ready to vote for them. That is why I take Anker listings with a grain of salt and do a little bit of research before buying.

Before you go poo-pooing the 15W charge spec. Check your phone's max charge rate. If you have a Galaxy S24 your max charge is 25W, unless its an Ultra or 24+, then its 45W. Most phones are 27W.

Sure it has many use cases, but at that price? No way.
