Batteries...
Modern life would be very difficult without the use of batteries. Over the years battery technology had changed greatly with more power and less weight. Consider how hearing aid technology fueled smaller devices, iPhone ear buds go for hours on a single charge.Probably the least improvement is the automotive standard 'wet-cell' car battery. Heavy, but supplied lots of high current.
Lithium-Ion and lithium-polymer batteries appear to be everywhere powering all types of electronic devices... especially cellphones.
The problem is they are volatile if mishandled. Overcharging a Lithium battery can cause an explosion with the battery emitting toxic fumes. A while back I read a story about a girl who shipped her phone between the mattress and pillow. This insulated the heat dissipation while charging. She was lucky it only smoked the phone and pillow. Other devices actually explode.
I order lots of batteries and the packages have warning labels on the box.
Airlines have restrictions for traveling with batteries. New generation cellphones are sealed, so you cannot tamper with the battery, but proper charging care is essential.

What is the best portable battery charger for phones and tablets out there?
I'm looking at this one.
50000mAh Dual-USB Waterproof Solar Power Bank Battery Charger for Cell Phone iPad Tablets
At $30. if you use it on a trip for backup to the wall charger that came with your device, you should be okay.
