All I want is a sure thing for my i-pone and i-pad. I don't know what all of these numbers mean. Can someone recommend the best of the three choices? Please.

LulamAh is Milli ampere hours or a measurement of how much power can be stored in the battery. You iPhone (depending on model) can range from 1600 to 2900mAh and iPad from 6000 to 11500mAh. Like car gas mileage the actual tends to be lower and degrades over time but you can divide these numbers into the size of the battery pack to get an approximation of the number of charges per device. As mentioned in an earlier post quality matters. Cheap no-brand high-capacity batteries sound great but have a tendency to transfer only about 60-80% of the stated charge and degrade rapidly over-time. Energizer is built to higher standards to last longer and provide better performance and that is why they can offer a 3Yr Warranty.
The 8410 and 10410 models are made for charging smartphone and tablets and have one USB port for each so you can charge one smartphone and one tablet at the same time. The model number is also their mAh charge capacity. The XP18000 can charge up to three devices and includes the cables and tips to also charge notebooks and laptops. You also get the benefit that you you can order and receive free up to 2 free tips per year so as you upgrade devices you are assured you can keep using this battery.
Hope this helps.

RHujarYou are almost correct. mAh is the amount of milliamp-hours it can store, but this is not necessary the power it can store, as power is measured in Wh. As these units are made using a single Li-Ion cell that is 3,7v you will need to multiply the mAh by 3,7 to find the Wh. The USB standard is 5V, so the 3,7v are upconverted to be able to charge other units, losing some % of capacity due to inefficient electronics.
I feel batteries like this should be described in Wh, as that would describe the actual stored power better..

OppholdsnesYou are technically correct. But we are trying to simplify and mAh is the current standard in reporting.
