Arcadia ACD66 Power Bank

The ACD66 was delivered with Amazon's usual promptness. Ordered on 26th May, delivered early on 31st, and that included a weekend and a Bank Holiday. Well packaged.

The ACD66 is supplied in a hard plastic case, which includes the ACD66, a brief, but adequate, instruction leaflet, a coiled cable, and a couple of adaptors.

The supplied cable combines with the two adaptors to give you either a USB A to USB micro, or USB A to USB mini cable.

USB A is the larger USB port that you will have on your PC, the USB mini is extremely common on portable devices, including many `phones. The USB micro is the newly adopted standard for `phones, and is the one used by all `phones that I have access to.

The ACD66 is a very attractive unit and appears to be well made. The upper surface is glossy piano-black, the underside has a slightly rubberized texture, so it should not slip about. The edge is surrounded by a silver strip. It is a little larger than I had anticipated, but considering the declared capacity, that should not have been a surprise.

The unit has two USB outlets rated at 1A and 2.1A. Although it is not mentioned in the instructions, the packaging declares a 3.1A output, implying that both outlets may be used simultaneously. There is a micro USB socket for charging, an ON/OFF switch and four blue LEDs to indicate charge status. This all combines to give a very clean and attractive design.

The unit arrived partially charged and took about 4 hours to be fully charged when connected to my laptop.

I bought this unit on the strength of its claimed current capacity. I have previously used similar devices from Kensington and iDol, but they were both unable to supply sufficient current to charge a smartphone, they cope with a DS but are not much use otherwise. Well I have not been disappointed the ACD66 has plenty of `muscle'. I don't have an iPad, but in order to see how the 2.1A outlet would cope I connected a passive USB hub and was able to simultaneously charge three smartphones (Orange San Francisco, Moto Defy and an iPhone 3GS). I have also left the unit unused for a week and there was no apparent loss of charge.

All in all an excellent device, which perfectly meets my needs for reliable, solid standby power? Thoroughly recommended.

This is my second portable battery, and it's as equally useful as the previous one I had brought (http://www.amazon.co.uk/New-Trent-iCruiser-IMP1000-Blackberry/dp/B004CHMP50).

The ACD66 weighs about 190g, as opposed to the IMP1000 at 280g. This is fine, as the ACD66 is about 2/3rds the weight and capacity of the larger unit. The unit has two outputs - 1A and 2.1A. Although the 2.1A is meant to be for tablets and the like, there is nothing wrong with using the 2.1A for phones, as they only draw the amount of amps they need. Therefore, this unit has a distinct advantage over the other battery I have, as it can charge two phones at the same time. A downside is that this unit can only be charged via USB - this does take a long time so best to do this overnight.

Another nice benefit of this battery is the "telephone cord" type cable which comes with it (see uploaded photo) - this is great for using when travelling. The LEDs have plenty of different states, so it is easy to approximate how much capacity is left in the unit. The unit is very shiny, so this attracts fingerprints easily. I'd have preferred the whole unit to be a matt slightly rubbery texture as the base is.

Overall this is a great battery, and would make a great gift for someone who is into their technology, as it really is very handy.

The product was out of the box use. Weight 197 g for the battery pack itself. Nice and solid design of the Battery Pack, and for my purpose nice with the twisted USB cord- but the adaptor peaces was of poor quality(and only two - so limited use of different devices, but no surprise for the buyer in this regard). Actually I have already broken the Micro USB adaptor, and looking for a replacement.
Before this happened, the device did it's thing well, quick charge of cell phone from 5-100% in approx. 1:30 (wildfire), and long duration (approx. 5-6 full recharges of the phone). But to me the most important thing was that I could let my phone run Bluetooth, GPS, Full screen light, and all signal for hours while using it for both HR-monitoring, GPS and sports-tracker while on my road bike, and the ACD66 capacity by far out-ran my endurance on the bike..
Just a shame about the adaptor quality - as it is a device made for keeping you portable device power on the go, everything in the pack and not just the battery pack itself should be made for this purpose.
