It is a crap, do not do my mistake.

I haven't put this through too many tests, but I find the solar component charges very very slowly.

I was really excited to see this solar version of an 8000 mAh battery because it could be a wonderful accessory to charge a device when I couldn't get to an outlet. Unfortunately, the solar component just doesn't work -- more on that later. If I charge the battery using an outlet, however, it's a fantastic external power bank, albeit larger (because of the solar panels) than the usual.

The power bank has two out ports, one 1A and the other 2A, the last one critical for charging an iPad. The 5V input uses a standard microUSB cable for charging. I like that it has an on/off button for conserving a charge, although I can't figure out how to tell whether it is on or off unless I have a device attached. It has four, blue LED lights that blink when it is charging, either by wall outlet of light.

As for the solar, I've had the battery on my window sill for five straight days, and it can't even charge my iPad one percent of its total. It transfers power to my iPad, using the 2A output, for less than 15 minutes. I thought that maybe the solar cells are used not for storage (that is, not to charge the battery itself) but for transfer while it was in the sun. Nope. I checked with the company to confirm that I did not receive a defective solar cell, and they told me that the solar cells were for emergency only. Unfortunately, my experience shows that solar energy cannot be used even in an emergency. It doesn't store the charge, and it doesn't transfer it directly. I don't understand the purpose of including solar cells on this otherwise good power pack.

The type of people who will likely consider this external battery are those who camp, hike, or want to be able to charge devices during an extended power outage. This battery will not work in any of those conditions. It will work, however, if it was charged at home. Note: I received a sample for review.

I received this product in exchange for this review.

The battery backup is handy when away from home or when not near an electrical source to charge your device. It has two USB ports for charging the 1A and 2.1A devices. It also has an input port to charge it from any 5V USB output, like a computer or wall charger. The 1.5W solar cell on it is of dubious use though. For its 8000mAh battery pack, it would take at least 40-50 hours of direct sunlight to recharge it. It's nice to think you have 'free' power from the sun, but this unit will not be very efficient in that regard.

The manual provided is readable, but difficult to understand. Fortunately for OXA, this device is pretty self-explanatory. You charge it up, then connect your device to it to charge the device. Find your device battery's mAh rating and divide that into 8000 to give approximately how many times it will recharge your device.

If you really want solar charging, you might take a look at the Voltaic Systems 1023 Fuse 10W Solar Laptop Charger, 14-20V/4A Input, 16000mAh, 60 Watt Hour Capacity, Silver. I got this for my son while in the Army in Afghanistan and he was able to charge his laptop with it.

This review is from: OXA 8000mAh Solar External Battery Pack Portable Backup Charger Power Bank for iPhone 5S 5C 5 4S 4, iPad 4 3 2, iPad Air Mini 2, iPods, Samsung Galaxy S4 S3 S2 Note 3 Note 2, HTC One, LG Optimus, Sony Xperia Z, BlackBerry Z10, Nokia Lumia 520, Kindle Fire, Google Nexus, Microsoft Surface 2 and Most USB Powered Devices (Black) (Wireless Phone Accessory)
I like this battery that I received as a sample because it fits in a pocket. Although a little heavy for pants pockets, it holds a lot of power.

The iPhone 5 battery holds 1,440 mAh and this battery holds 8,000 mAh. Of course it's significantly larger than the iPhone battery. And it can fully charge 5.56 of the iPhone 5. It might hold all the power needed for a 5-day+ camping trip.

Also, I like that it has two USB output ports and lots of connectors along with a cable. It can charge any of my portable devices.

I like the appearance a lot - the shape and even the feel of this battery.

The battery itself is great after charging this from a wall outlet but its solar function does not seem to capture enough of a charge to be usable. I have attempted to solar charge this device and trickle charge a device through the solar function, but I had no luck with either. The size of this device would be great if everything worked, because it doesn't, I wouldn't recommend this device as an external battery.

The high capacity SOLAR power bank is PERFECT for those high demand electronics - both during summer storm season, winter storm season and all those summer treks to the park, the beach, or the cabin where power is not as readily available. Just remember it's solar, it will take longer to recharge, or you can manually recharge via USB. Having worked in disaster work and been a road warrior, I find devices such as this invaluable - particularly solar models. I keep several USB LED lamps handy - together they are a great emergency lighting system when the power goes out! Though I received the OXA external battery for reviewing purposes, it's been working great, I highly recommend!

OXA Solar External Battery with its decent capacity of 8000mAh is well made portable battery that can be used for simultaneous charging of two phone or other portable devices, though its solar charging feature was a bit disappointing.

As was the case with few other products of OXA which I received for review purposes, this battery also shipped in package box that well-preserve product from the possible damage during the transport. Inside the package beside portable battery, customer will get four different portable connectors, microUSB cable and DC connector.

The battery can be used mainly for phone and tablet devices and due to its two ports, one of 1A and other of 2A, it can be used for simultaneous charging keeping in mind its 5V input. The nice add-on is its four LED lights that are placed on the device so that the user could better assess the amount of power remaining in the battery or charging status.

As already mentioned, the only disappointing characteristic about this product is one that attracted me most to this device - solar charging. The 1.5W solar cell on device is not of highest power therefore it would take around 50 hours of direct sunlight to recharge this power bank which makes it not efficient and almost unusable.

This is another product that I tried from OXA and in terms of in terms of investment and received this company manages to do a good job - speaking both in terms of their price, design and quality. 8000mAh battery is unfortunately not so good example because of solar charging issue but besides that this power bank is product worth considering.

I received a sample of OXA 8000mAh Solar External Battery Pack Portable Backup Charger for the purpose of testing and unbiased review, while all the presented information is based on my impressions.
