Demand for electronic devices seems to be growing more quickly than the number of outlets available to charge them. Hoping to provide power to those in need, Eton has introduced a series of portable backup batteries, BoostBloc.

The BoostBloc comes in three power options, with lithium-ion batteries that provide an electrical charge measured in ampere-hours. For instance, Eton’s most powerful, the BoostBloc 6600, provides 6,600 milliampere-hours, enough to fully charge a smartphone three times.

The charging blocks in the BoostBloc series range in price from $40 to $100. Each includes a micro USB cable, which is used to charge the block, and at least one USB port for power output; the BoostBloc 6600 has two USB ports to charge two devices at once.

In a recent test on a smartphone drained to 11 percent of its power, the BoostBloc 2000 gave the phone enough power to continue playing music for a couple of hours while still charging the phone back up to 92 percent.

For outdoor enthusiasts, Eton also offers the BoostTurbine 2000, a power charger with a hand-cranked generator that provides juice with a few turns of the wrist. A solar-powered charger also is available.

Jabra, best known for its Bluetooth phone accessories, is making its first foray into Bluetooth premium headphones with the $250 Revo Wireless.

While the Revo has fashionably overstated bass sound, it also has an equalizer app so you can dial the bass down to a more realistic level -- or up to a brain-punishing thud.
