How to extend your smartphone’s battery Life with a Portable Battery Charger

By now you’ve graduated to the “Smart” Crowd as I’d instructed you to do in How to transfer Phone Contacts and Data from your Blackberry to your Apple iPhone or Google Android smartphone or Tablet even as the “In” Crowd tote their Blackberrys about Town.

Still, you may have notices that your smartphone has a habit of running out of charge ever so often when you need your precious to keep you entertained at the Bus Stop or to drone out that annoying Preacher on the JUTC Bus.


So what to do to prolong the Battery Life of your smartphone or Tablet? Not much really, as these Li-Ion Batteries are inherently unintelligent. It’s really up to how you use your device; you’ve gotta makes sure you don’t have any app running on your smartphone and also set it to Airplane Mode when you’re on your commute home.

But if you’ve done all that, then perhaps it’s time to invest in yet another gadget that won’t cost more than US$100 (approximately JA$10,000) for you to buy online. It’s called a Battery Charger and I’ve got a nice list of them here from Amazon that are great for recharging your smartphone or Tablet and saving you from the boring World around you:

  1. US$100 RAVPower Xtreme Portable External Battery Charger
  2. US$20 EasyAcc Slim Power Bank Charger
  3. US$25 Lumsing Harmonica Style Portable Power Bank
  4. US$30 Jackery Bar Portable Charger
  5. US$46 Anker 2nd Gen Astro3 Portable External Battery

Here’s a comparative listing of the Battery Chargers and their respective specs before you run unto Amazon to order one:

Name Capacity Output Weight Price (US$)
RAVPower Xtreme Portable External Battery Charger 23,000mAh 3 ports 560g (19.75oz) $100
Lumsing Harmonica Style Portable Power Bank 10,400mAh 2 ports 236g (8.35oz) $25
Anker 2nd Gen Astro3 Portable External Battery 12,000mAh 3 ports 300g (10.56oz) $46
Jackery Bar Portable Charger 5,600mAh 1 port 154g (5.44oz)


EasyAcc Slim Power Bank Charger 5,000mAh 1 port 133g (4.69oz) $20


So it’s settled then. With a variety of prices and options, until smartphone Battery Life is measured in days or weeks rather than Hours, you’ll eventually have to get one of these, especially if one day your travels take you into the Rural Areas.
