Onaji Pawa Card - Credit Card Sized Power Bank and Data Cable with 3 in 1 connector (Sunday Times Best Buy, MacFormat, PCAdviser)

Great product. It's small and neat, so very easy to carry about, and it works! However, the instruction leaflet is misleading. It says the LED flashlight comes on when the unit is fully charged. When it didn't charge my phone, I emailed Onaji for advice. In fact the LED goes out when it's fully charged. They are amending the manual.

We bought two of these nifty devices for Xmas presents for our son and his girlfriend. They both have the latest iPhones and were concerned about battery life when outside of the home , at work and travelling. This neat little device although not as powerful as other versions is small enough to sit inside a wallet, purse or bill fold and can be carried at all times to act as emergency power. Just what was needed, a great product which arrived quickly and safely. Comes with a full range of connectors to work with any mobile phone.

Recommended in The Times but failed to charge phone to above 10% and therefore pretty useless and connector so fragile broke away! All in all very disappointed.

Thought this was going to be a good product after review in Sunday Times. Its good if you just want a multipurpose connector - but it only managed to charge my iPhone 4s by between 10%-20% of its capacity - so not what I wanted it for - so returned it.

Nice idea but I'm not sure if performance is up to maker's claims. After fully charging the power bank I failed to get any response from it on my partially-charged iPod touch (30 pin connector) or iPhone 5 (lightning connector). However a well-charged Samsung phone acknowledged the connection and appeared to accept the extra charge. Waiting to hear from the makers and other users if this is normal. Do the Apple devices have to be in "battery flat" condition before the charger will work? Watch this space!

After browsing through an endless list of wallet-sized chargers I finally found this little gem. Cables built into the device itself, supports pretty much every smartphone thanks to the 3-in-1 cable, also comes in handy as a data cable. The built in torch isn't going to light up a room, but perfectly usable in small spaces.I've only given this 4 stars as the cables feel a little delicate and might rip out if I'm not careful. Won't know until I start using it, may try using some sugru to secure it in place.

Clever product emergency back up battery the size of a credit card and a torch (led) only in emergency though till a proper charger is attached

The battery in this item expanded and broke the device during the first charge... This could have been very dangerous. I have returned it. Great idea, but poor quality.
