Portable Chargers - or how to make your phone last all day

A friend mentioned earlier today that she wished her phone could hold a charge during one of her longer days.  It might be 14 hours from when she leaves the house in the morning, until she gets home.  It would be nice if her phone could last as long.

I told her about portable chargers, and showed her my 15,000 mah Anker.  She made a note of it.  

When I got home, it occurred to me that she probably spelled it Anchor in her notes.  I found myself about to write a long email to to clarify, and add some extra points.  

Instead, I thought I'd make this blog post.

A portable charger is a device about the size of your phone, although it can be larger and heavier, that is in itself a separate battery.  Being that it is nothing but a battery, they can recharge your phone several times over.

You have seen these a the checkout of your pharmacy.  The ones there are small tubular ones that look much like a lipstick.  Those are about 2200 mah.


Google definition:  A milliampere hour (mAh) is 1000th of an ampere hour.

Phone batteries are generally 2000 to 3500 mah.  Therefore, if your phone is 2200 mah, and your little lipstick Portable Charger is also 2200 mah, it means you can charge your phone a single time from it.

Larger batteries are available.  Personally, I like the Anker brand and have bought several for the family and as gifts.

They have one giant one of 25,600 mah.  That would recharge a 3000 mah battery over 8  times.

As of today (June 2015), that sells for $80 at Amazon.

I think the way to find the best value is to discover the cost per mah.  That 25,600 mah charger for $80 would get you 320 mah per dollar.

A 3200 mah device for $20 would be about 120 mah per dollar.

The closest to the one I own is a 16,000 mah for $40.  That's 400 mah per dollar. I think that is a pretty good value, but I didn't do the math for each of the many Ankers Amazon offers.

The Portable Chargers generally do not come with their own charger, but charge from any charger for an Android phone.

They are dirt cheap.  Here are a few I found on Amazon..

Using Automagic to get around a bug in Android Auto

I recently purchased a Google Pixel XL 32g phone. It is by far the best phone I've owned.

It is great company on my daily commute. The Android Auto app warns me of traffic, plays my podcasts for me, and lets me dictate text messages.  I've combined it with ReadItToMe so that my incoming text messages are read aloud.

I noticed on my first afternoon commute though the Do Not Disturb icon was turned on on my Android watch. At the next traffic light I discovered that Do Not Disturb was on on the phone as well.

A Google search at home found I was not alone in noticing/suffering this.  The Android Product Forum had mention of it.

People first reported this back in November 2016, so hopefully a fix will be coming.

Meanwhile, I worked out a workaround using AutoMagic.

The flow below detects the launch of Android Auto and then turns off Do Not Disturb by setting the Ringer on, and turning the audio volume up. I have tested it briefly here at home, but not yet on a commute.

Recording your own notes with Google Voice

Note :   April 2016:  Frankly I don't know if this works anymore.  It is 7 years old.

I stopped using this when Google Now became useful on my phone, and I could dictate reminders using it.



I found a way a while ago to use Google Voice to record a personal note, transcribe it, and email it to me. A recent Lifehacker post "Five Things We'd Like to See in Google Voice" lists that need as their #5 request, so I realized what I'd figured out is not common knowledge.

In GV's Contacts, create a Group "Special Transcription"

To avoid listening to my standard voice mail when I call, I recorded a short voice mail greeting for this group simply saying "Record note now"

I added a contact with my own cell phone number as the only number, and made it the sole member of this group.

In GV's phone settings, I edited the settings for my cell phone. In the section "Direct access to voicemail when calling your Google number from this phone?" I se…

Your First Day with Evernote

I've written many times before about Evernote.  I love this program.  It is my brain's memory on steroids.  I have over 6000 notes in it now.  And I keep finding ever more uses for it.

While originally written in 2009, this post has been frequently updated.


New January 2012:  If you like what I write about Evernote, check out my 136 page e-book,
 "Get Productive Fast with Evernote".  Just $10.

Sunday October 11, 2009 I wrote about Evernote in my print column, Family Tech. If you are wondering what is Evernote, and why would I want to use it, start with the column.

I promised in that column this post to help new users get efficient fast with Evernote.

I thought I'd write a quick plan for someone's first day with Evernote. This is really meant for after you've installed the client to your computer, so this picks up after you've gone to  Evernote's Get Started Page and created an account and downloaded and installed a client for your primary computer.
