5.0 out of 5 stars Another solid product by New Trent, September 10, 2011

This review is from: New Trent Arcadia Pack IMP70D 7000mAh USB External Battery Pack and Charger for iPad2, iPad, iPhone 4S 4, 3Gs 3G (AT&T and Verizon), iPod Touch (1G 2G 3G 4G 5G), Motorola Droid Phones, HTC Android Phones, Blackberry, Samsung Galaxy S, Samsung EPIC, Nintendo, Sony PSP, and much more (Electronics)

EDIT (10/14/2011): When reading this review, please note that when I got this product, it was called ACD66 and its capacity was rated at 6600 mAh. Since then, this product's name has been changed to IMP70D and its capacity re-rated at 7000 mAh.

EDIT (10/22/2011): I tested the 2.1A output on an iPad 2, and the IMP70D is indeed able to charge an iPad. The iPad was charged from 42% capacity to 69% in 90 minutes while being lightly used.

Original review:
I own both the IMP50D and this update to the IMP50D, the ACD66. Overall, the ACD66 is a very solid portable charging solution for electronic devices that can be charged from a USB port. Its 6600 mAh capacity and two USB charging ports (1.0 A and 2.1 A) can charge multiple devices multiple times over multiple days before needing to be recharged. If you need a lightweight portable charging solution, you will be satisfied with either one of these devices. I list a few difference between the two below, and if you are thinking about getting the IMP50D, take a look at my review of it for a few things you should take into account when using it. If you are not satisfied with whatever you get or if you think something is wrong with it, contact their customer support--they are VERY responsive and helpful.

Differences between the IMP50D and the ACD66 (most are improvements; some are a matter of opinion):
* The ACD66 has 1600 mAh more capacity (6600 mAh vs. 5000 mAh)
* At 8oz and 3.5 inches wide, the ACD66 is 3oz heavier and 0.5 inches wider (other dimensions are the same)
* The two charging ports on the ACD66 have higher output limits (1.0 A and 2.1 A vs. 0.5 A and 1.0 A)
* The ACD66 has a slightly rough, no-slip bottom surface; the IMP50D slides easily
* The ACD66 has a micro-USB charging port; the IMP50D has a mini-USB charging port
* The ACD66's power button is smaller and more difficult to accidentally press
* The ACD66 has a built-in auto shut-off function; the IMP50D does not
* The two have different LED power-indicating systems
* The power button on the IMP50D turns the devices on and off; on the ACD66, it only turns the ACD66 on--the ACD66 turns itself off after devices being charged are disconnected or fully charged

Read on if you want details on some of the things I mention above and my review broken down by pros, cons, and mixed opinions.

Pros:
It seems like this update to the IMP50D has resolved a number of issues that I experienced with the IMP50D. Firstly, there now appears to be an auto shut-off mechanism that turns the ACD66 off when my devices are fully charged. The ACD66 does not drain through the night after my devices are done charging. Secondly, the smaller button seems more difficult to accidentally press, so I have been less concerned with that in the ACD66 than in the IMP50D. Thirdly, although the LED power indicator bar on the ACD66 is not as pretty, it is also not as bright and as disruptive as the LEDs on the IMP50D when using the ACD66 in the dark (which is when I often charge my devices overnight while I sleep...in the dark).

One odd thing I did notice specifically with my Samsung Intrepid phone is that when it is connected to the IMP50D, even if the IMP50D is not turned on, the charging light on my phone turns on and the phone thinks that it is being charged. This issue no longer occurs with the ACD66.

Aside from these improvements over the IMP50D, I like the fact that the two charging ports output higher currents, 1A and 2.1A. The 2.1A output is supposed to be enough to power an iPad, but I'll have to wait until I visit my parents next to test it on theirs as I don't have one of my own. It also seems like the 6,600 mAh capacity of the ACD66 lasts for a very, very long time. It seems to last through about three days of substantial use. Definitely a workhorse!

Cons:
It seems that the power indicator LEDs jump very quickly from three LEDs (60 - 80% capacity) to one flashing LED (< 20%), much more quickly than from four LEDs (80 - 100%) to three LEDs (60 - 80%). I've only gone through two complete cycles so far, so I plan to continue observing this.

Mixed opinions:
Size vs. capacity. The ACD66 is larger and heavier than the IMP50D (1/2 inch wider and 3 oz heavier), but it also has a larger capacity (6,600 mAh vs. 5,000 mAh). For my purposes, I would rather have the smaller size as opposed to the higher capacity because I am out all day a lot and therefore try to minimize the weight and bulk of what I am carrying. If I could design my own battery pack, I would have the functionality of the ACD66 in a battery the size of an IMP50D, even if I had to give up the extra 1,600 mAh.

The power-indicating LED band. It shuts off a few seconds after the ACD66 is turned on. This definitely conserves power and allows for less disruptive operation in the dark, but you also have no way to know if the unit is really on or not. One has to trust in the indicator lights on the units being charged. Would I really want the LEDs to stay on? Probably not, but it would be nice to know with confidence that the unit is actually on. How to achieve this? I don't know. Mixed opinion.

There also seems to be no way to really turn off the ACD66 without disconnecting or fully charging all devices being charged and waiting for the ACD66 to turn itself off. Personally, I like to be able to turn off the power source before disconnecting my devices, but I don't think this really makes a difference. So again, a mixed opinion.

This review is from: New Trent Arcadia Pack IMP70D 7000mAh USB External Battery Pack and Charger for iPad2, iPad, iPhone 4S 4, 3Gs 3G (AT&T and Verizon), iPod Touch (1G 2G 3G 4G 5G), Motorola Droid Phones, HTC Android Phones, Blackberry, Samsung Galaxy S, Samsung EPIC, Nintendo, Sony PSP, and much more (Electronics)

I spent a lot of time researching different battery backups, and I've owned several, so I know the pros and cons of these things and this one is the best value and has the best features. First of all, it has a ton of power and is quick to charge. But probably the best features are the ones you don't think about. It can be charged with your computer instead of a wall outlet, in case you're low on plug adapters/converters (or just wall outlets!) It can also be charged with your iphone a/c adapter, so you only have to travel with one of those. It comes with adapters for other devices besides the iphone, so it can charge all your gadgets. It has lights on it that tell you how much power is left, which is helpful. The versatility of this device is what makes it uniquely superior to others on the market. A lot of thought went into the design of this product, and you won't be disappointed!

5.0 out of 5 stars Solid performer in a great form factor, October 4, 2011

This review is from: New Trent Arcadia Pack IMP70D 7000mAh USB External Battery Pack and Charger for iPad2, iPad, iPhone 4S 4, 3Gs 3G (AT&T and Verizon), iPod Touch (1G 2G 3G 4G 5G), Motorola Droid Phones, HTC Android Phones, Blackberry, Samsung Galaxy S, Samsung EPIC, Nintendo, Sony PSP, and much more (Electronics)

I bought the IMP70D battery pack right before a long trip after quite a bit of research and after a brief experience with a friend's IMP99D, which saved the day. I chose the IMP70D because of its flatter and cleaner form factor despite the slightly lower battery capacity. It does exactly as promised, reliably charging all manner of devices from iPhones to iPads (simultaneously) and of course non-Apple products as well. Included in the package is a relatively short pigtail cord with standard USB on one end and mini/micro USB adapters on the other. Be aware that a wall transformer is not included in the package -- your existing Apple mini-cube transformer or other USB power source will do the trick. One feature this newer model has that the older ones apparently do not have is a smart sensing (power saving) capability which turns off the battery pack once your device is fully charged. Interestingly, the IMP70D does not get hot when charging (or discharging), likely a sign of good power and thermal regulation, which should lead to a longer service life. Some of the previous generation battery packs had cooling vents but this one appears to not need them. Overall a solid product that will keep you mobile.
