Brunton continues to expand portable power devices and gadgets with the new Brunton Sustain 81-00019 battery hybrid portable battery power device. Brunton Brunton Sustain 81-00019 battery features an internal lithium polymer battery that you charge at home, in your car or from your computer so you can then power your USB gadgets like portable electronics, Smartphone, gps, laptop, pda, review, android, iPad, Compaq computer charger while off the grid. Brunton Sustain lithium polymer battery that has a storage capacity of 73 watt hours. Charges most USB gadgets including cell phones, digital music players, digital cameras and GPS devices; also charges 2-way radios and portable game consoles.

Most Laptop Batteries are manufactured by all the leading companies in the market like Samsung, Toshiba, Panasonic, Acer, Compaq, Dell, Gateway, HP, IBM, Sony, and last but certainly not least, the new hot Apple iPad. OK, first the boring tech stuff. While the iPad is very power-efficient, it doesn't hurt that the iPad has a huge battery inside. The iPad gets its power by 3.75V rechargeable battery(X2 wired in parallel to get 7.5 volts), 24.8 watt-hour (6.5 Amp hour). The 25 watt hour lithium-polymer battery provides the iPad the battery power for the advertised 8 - 10 hours of use. For comparisons, the iPhone 3GS has a 4.51 watt-hour battery and the Mac Book Air has a 40 watt-hour battery.

Ten hours of battery life on a device like the iPad may or may not be enough depending on your usage pattern. The iPad "up to" 10 hours of battery life depends whether you’re web surfing, reading, watching movies or listening to music. When you hear the words "up to" it might cause you concern, but there would be no other way to word it since everyone needs a wide a range of iPod battery power draws. Anyone that’s ever used a mobile device knows that battery life varies depending on what you’re doing with the device. The iPad is no exception so... no big deal. Especially since this iPad battery review is about how to boost the existing battery. However, we should say that continuously use of Apple iPad Bluetooth keyboard, while playing music with the Bluetooth headset, cut the iPad battery life nearly by about 1/2.

The Brunton Sustain 81-000018 73 WH rechargeable battery is a very cool compact portable device that Brunton just came out with. The additional 73 WH of energy will add about 38 hours of additional off-grid use of the iPad (Again, depending on what you are using the iPad for). You might remember from high school physics that when comparing battery capacities what really matters is watt hours, which is arrived at by multiplying ampere-hours and voltage. The Brunton Sustain portable battery has a capacity of 73 watt-hours. That’s enough to light a 100W bulb for over an hour, or to boil 3 cups of water which is an incredible amount of energy for a small lightweight portable battery like the Brunton Sustain.

Charging the iPad batteries takes some time. The 10 Watt standard power adapter will power the iPad in about 3 hours which is quite a bit faster than charging via USB from a laptop. There have been some reports of the iPad failing to charge when plugged in via USB. MacWorld offers a good overview of what's going on, mainly that some older, lower-power USB ports just don't have the juice to power the iPad. Suffice it to say that the 10 watt USB charger is your best bet for recharging in a hurry.

Though, in the interest of full disclosure we have not officially test the theory, charging the iPad from the Brunton Sustain should be at least comparable to the 10 watt iPad power adaptor if not better. Amps X Volts = Watts. Brunton Sustains' output set at 12V (output is adjustable) is 3.2 amps (3,200 mA) 3.2 amps x 12 volts = 38 watts. The energy capacity of a battery is usually expressed indirectly in ampere hours; to convert watt hours (wH) to ampere hour (aH), the watt hour value must be divided by the voltage of the power source. This value is approximate since the voltage is not constant during discharge of a battery.

The Brunton Sustain has multiple adaptors that come standard. If we attach the extra battery to the USB port and then surf, the Brunton Ipel with a rated energy capacity of 73 Wh adds another 45 - 55 additional hours of usage to the iPods' standard 8 - 10 hour battery.
