compact high-capacity

A compact, solid-feeling powerbank with a rubberized exterior and a decent capacity. It's nice looking and has a better charge/discharge rate than many early-generation battery packs.

99Digitals has gone for simplicity in this USB battery pack: a minimalist design, one output that delivers the battery's maximum output, a 4 LED capacity gauge. A short, flat USB to microUSB cable is included. There's an easily overlooked low-lumen "flashlight" LED that's too dim to be useful, and a power button.

Charge and discharge are both decent, with the battery drawing 5-6W (at the wall) when charging. Charging a connected device is brisk, with my LG Nexus 5 topping up as fast as it does from its native AC adapter. This is better performance than many USB batteries I've tried, and superior to many USB hubs. Even allowing for power lost to overhead, the 7800mAh capacity is enough for 2-3 full charges of the typical smartphone's 1800-2300mAh battery.

The no-skid ribbed exterior is a nice aesthetic variation from the usual battery, but the matte black finish keeps the rubber from looking cheap.

In today's mobile-centric world, it's important to keep devices charged up. But depending on wall-power or car adapters can mean a lot of plugging-and-unplugging-- short charges that are bad for battery longevity, and ineffective at keeping a good charge (unless you're willing to be tethered to the wall for an extended time). With a USB powerbank, you can just take the power source with you, unplugging when the device is done charging up. I keep a USB battery in my vehicle, office desk, and in all of my commonly used travel bags.

The market for USB battery packs has become quite saturated. But this unit, with its compact minimalism and solid power performance stands out. Recommended.

The quality and efficiency come in small package, and this microSDHC module is no exception. It is suitable for smart phones, computers and other devices using microSD memory. I recommend this product blindly.

Note: The supplier kindly sent me a review sample for evaluation, with a request for an honest and impartial review. 

Note this is a review for the Ultra-slim 4-port USB hub.

This is a very small and easily pocketable 4 port USB hub that is ideal for packing and carrying with your tablet or laptop.
It measures only 6 x 4 x 0.8 cm so is about as small as you can get with a 4-port hub with full-sized USB sockets. The input comes via a hardwired cable with full-sized USB plug. To keep things small and tidy the cable is only around 15 cm long.

The output ports are arranged, one at the end opposite the cable entry and three along one side.

If you're struggling with a single USB port on your tablet or laptop this transforms things so theres no more need to keep swapping devices and the fact that it runs at USB-3 speed means youll get the best performance out of your peripherals.

Theres no option to provide additional power to power hungry USB devices, but you wouldnt expect that where the design aim is to keep things compact.

A really neat and handy piece of kit to slip into a pocket of your laptop or tablet bag.

I have already recommended the product to several of my friends. Excellent performance and capacity for the price.

This was ranked as a best selling item, and I can see why. This has got to be one of the most convenient and compact electronic products I own. I am not a big user of the cloud for security reasons, and this drive is perfect as a backup utility for my laptops. The extremely large capacity (2TB) is nothing I've ever found in such a small lightweight device. Plus, the 3.0 USB allows for quick transfer of data. Overall, I am very happy with this product and recommend it to other prospective purchasers without reservation.

Nice reliable little power supply.  The powercore is compact at 2 1/2 inches X 4 inches by 3/4 inch.  Can be fully charged in about 50 minutes in the house, also the car charges it overnight but I have never timed it.  I use it for my phone while commuting, and it charges even as I surf or email.  The charge is even and steady.  I would give it 5 stars but for one thing.  It can only charge my phone (a LG G5) once.  For its physical size, I expected perhaps 2 or 3 full phone charges per powercore recharge.
I would recommend to a friend.

This Gigastone microSDXC UHS-I Card is Class 10 and certainly is fast enough for normal use.  It functions perfectly as extra storage for a notebook or tablet computer.  I'm using it with an older Samsung Chromebook to extend the 16GB internal drive for file storage and to access audio and video files while travelling.

It is waterproof, temperature proof, X-ray proof, and magnet proof, and is backed by a generous warranty, so no worries.  An SD adapter is included.  The 64GB card is preformatted with exFAT.

At this time, the 64GB card hits the sweet spot for cost per GB.

This was just what I have been looking for to meet my offsite backup needs. It's 93 MB capacity will backup my  system nicely (using Retrospect), and it is small enough to carry in my back pocket (in its compact and convenient and protective leather carrying case)...so I have a backup offsite with me where-ever I go! On a Mac G5, it runs fine using ONLY USB power, so it couldn't be more convenient since I don't have to do anything but plug it in the USB port and its good to GO. Backups take place at an average data  rate of about 350-400 MB/min (about 3 min/gig). Thanks DES for meeting this need.

I have been using this portable hard drive on a Windows PC for approximately 3 months now, and I love it.  The small size is very convenient, as it allows you to take it with you anywhere you go. I can fit this drive in my Netbook case, which makes air travel easier, as I can take all of my work and personal files with me. Unfortunately, I do not have USB 3.0 on my computer, so I cannot comment as to the performance on 3.0, but on my 2.0 USB computer, the performance is very good (without getting in to the technical details, let's just say it is MUCH faster than USB thumb drives.

I have not used the cloud storage or the back up and security programs that come with the drive, but it is nice to have those if you are looking to back up from a computer or store sensitive files. The shock sensor/protection system also provides some peace of mind, although the cord that I use is too short to allow for the drive to fall to the ground.

In summary, the design of this drive is sleek and looks good next to an HP Netbook and Laptop; and the performance of this drive has been more than satisfactory. I also love that it does not require an additional power source as the bulkier, larger desktop hard drives often do!

I travel a lot and having a compact, two-port charger that can handle high output is a definite plus. The AGPtek charger is small, about the shape of and a bit bigger than an iPad charger, but it packs a wallop. It's rated at 4.8A and I was able to draw darned close to that from its two outlets, as measured by a Practical Meter and a Legion Meter. Even at that high output, the charger barely got warm. The "Smart" charging circuitry makes sure that devices get as much power as they need, properly negotiating with Apple and Android devices for full power delivery. The distributor sent me a charger and asked for a review.

The folding prongs have a strong latching mechanism so that they won't fold in accidentally, and the blue LED illumination is from within the body, viewable around the charging ports but not obnoxiously bright as is the case of another two-port charger I have. This one is definitely going in my travel kit!

Compact storage device for one individual cd's or dvd's

This is very small, at 3.4 x 2.7 x 0.7", and has a wrap-around USB cord that makes it convenient to use.  Too bad the internal 1.8" hard drive isn't accessible/upgradable, but that might make it bigger.

It looks like there will be some competition for this thing in the near future from Plextor, with devices that are thinner (0.5" or 12mm) but otherwise a similar size, though without the wraparound keyboard.

These flash drives are small and compact yet they will hold a lot of photographs when transferring pictures.

True, this isn't the fastest netbook created, but with a decent-sized hard drive and multiple USB as well as a SD slot, this highly portable little PC is perfect for those vacations where taking tons of photos is a goal.  Every night I upload my daily snaps to this unit and then backup them up to Flickr and the Cloud.  Meanwhile I recharge my GPS, IPod and New Trent portable battery through the USB ports.  Fast enough to keep the fans back home in the States updated through the internet and webcam.
