Portable chargers for smartphones and tablets
While phones and tablets now get decent battery life, frequent travelers can stretch that life to the limit. Long days away from power outlets and heavy usage can drain even good batteries dry.
Portable power chargers are small battery packs that can be used during the day to top off batteries when they get low. They add very little bulk to briefcases and gear bags and can be lifesavers when needed.
There are dozens of portable chargers on the market, many from unknown companies that might not be good. This collection has been assembled based on personal recommendations from folks using them. It is thus a good place to start when looking for a good portable battery pack for your smartphone and/or tablet.
The prices and links for these gadgets are those from the charger manufacturer. Many of them can be found at online retailers like Amazon, so it's always a good idea to search online before ordering one.
Note that many of these OEMs are quick to push their products for use with iPhones and iPads, but with USB charging ports they will work with most phones/tablets.
These chargers will not work with laptops, as those require special high-power battery packs. Those are typically very big, heavy, and expensive, so they are not included in this collection.
The packs included here are by no means the only ones available — they are just the ones recommended to us. If you have another power pack that has served you well, please share it in the TalkBack below.
