Odds are the battery will wear out before the cable does. Even if it doesn't, they have additional ports. These are reinforced cables, and I view them as a net positive.

I have a couple of much cheaper no-name 20Ah battery banks (which do not do 87W, or anywhere close to it — only about 28W, but that's another story) and the cables are very useful, the problem with the cheap ones I have is the cables are super short which makes it awkward sometimes to position the power bank when connected to a phone. The cable on this looks to be substantially longer, which is a big deal if you ever dealt with (very) the short ones.

While I like Anker products, I believe the price is quite high for the capacity of the battery. However, if you need something like this, this should be a better product than some of the other products posted here which start with B — this is more likely to be close to advertised capacity (the other will be off by a good 20%), and keeps discharge to a relatively safe, and healthy for the battery ~1C max (<=1.2C if capacity is indeed 20Ah as advertised), whereas the other product will do over 2C, even 2.5C. This is a premium price for a solid product, I wish it was 25Ah (or even the FAA carryon limit of 27Ah = 100Wh @ 3.7V), but if you need one to charge laptops and will use it a lot, I'd pay the premium for a more solid product like this.

Read my renewest post to Bluevoyager308. You misunderstood what 65% mean.
Please read Anker's description and see their disclaimer about the capacity. This is not coming from me, this is from Anker telling you that you can only use around 11,000-13,000 mah out of the 20,000mah advertised capacity. They even have a very specific and clear example with mathematical formula.

FROM ANKER:
Quote :
  • The capacity reduction during charging is due to a 30% to 45% energy loss in the battery cells and conversion circuitry. Therefore, a fully charged Anker A1383 Power Bank (PowerCore 20K) offers an estimated 11,000mAh to14000mAh to power devices.
  • To estimate charging cycles, use this formula:
  • (Power Bank Capacity × 0.65) ÷ Device Battery Capacity Number of Charges.
  • For instance, charging a 3,000mAh device using a 20,000mAh power bank would offer approximately 4.33 charges

Nah. You are just an Anker fanboy.Veektomx is 88% $23 Ugreen 100w is 82% $55These to name a few and there are many out there that are far better than 65%. Maybe do a bit of research. 65% is far unacceptable unless it's wireless charging.
Where did you get 82% from for ugreen? Their Amazon Page literally has their rated capacity at 11,300. Way under 65%

Deal seems dead. Price was bumped up to $69 so with $15 coupon it's still $55.

Bought this for my Legion Go when I didn't want to be tethered to an outlet while playing power hungry games. Works great, basically doubles my game time, and recharges itself super fast. The built in cable is made well and has proven very convenient for times when I didn't have a USB-C cable handy. This is a great price
