Before I get into my question I just want to preface what I’m about to ask by stating that I am fully aware of 30 Watts being insufficient with regards to charging a MacBook Pro 15 whilst in-use. Especially not with the load I’ll be placing on the laptop.
Having said this;
I’m about to purchase a top tier, or rather the top tier MacBook. Considering this is rather expensive and constitutes well over 50% of my annual “expendable” income… not that I have any expendable income… I need to make sure my investment is well taken care of, and of course concurrently used to within an inch of it’s operational life.
It is thus, and among other things, that I am looking to invest as well in a premium external battery.
My question therein is twofold. Taking into consideration my above disclaimer, will a Power Delivery capable Anker Battery Bank meet the minimum requirements of the 15 inch laptop? And as stated, please take into consideration that I am not expecting any such current Anker product to charge my egregiously priced workhorse.All I’m seeking, within the scope of this post, is an answer insofar as whether such an Anker product will reduce the rate of discharge.
At times, and it won’t be often, I will need to extend the battery life of the specified laptop. Even if this means it just drains a bit slower due to supplemental power.
An example of such is the USB port provided in my Ford Fiesta. Whist actively using a device plugged into said port, say a 10.1" Samsung tablet for its GPS capability, the device does not charge per se. It does however ensure that I am able, on an extended trip, to reach my destination where otherwise I would have depleted the device’s reserves.
Continuing on the above, if the above is possible, would supplementing the laptop’s battery as such impact negatively; it’s longevity?
Finally, I have made an assumption that a (the) Power Delivery capable battery will be capable of charging the laptop while the laptop is powered off. Am I mistaken?
