This device gave me about 7 work days worth of action (still had 1-2 lights, could have probably went to 9-10) like advertised and is compact, fast charging and relatively light.

Very solid device.

I am excited for technology to evolve so that I can carry around so much power in a smaller form factor, but for the amount of energy this thing packs in it, it is a very good device

Device is durable and does not become hot during use.

Everyone who has a portable device should have one of these units

I love this device, its a fantastic device to have if the power is out during hurricane season.

one of the best devices i've purchased, in terms of usb powered devices, this has replaced an extension cord when poolside, camping, in the garage, etc.

I use them to charge off our solar panel battery bank and then charge our devices like phones, tablets, wireless mice, etc

Favorite new tech device and can’t wait to take it to Disney.

device makes a horrible squealing noise when charging my phone

So so many charges in this device - great or travel.

I can charge my iPhone 8 Plus multiple times as well as other devices before it needs to be charged itself

One to charge the device and the other for some other device but not a cord to support Apple devices

I was impressed with their determination to replace the defective device, which was received within a couple of days.

I highly recommend this portable charging device

I haven't had a dead device since I bought this

Love it, charges fast, I have fully charged my iPhone 4 times without charging the portable device and I still have enough charge to charge

It does take an entire night to charge it but aside from that it is a fantastic device.

Best charging device I have ever owned

Other devices I had were a lot cheaper and went through same workloads but lasted much longer

I bought one for my wife, she loves it, charges any device really fast

and I was thrilled to have this wonderful portable charging device

Good charging device 👌 charging it through the night gives two hours to charge iPhone and iPad for a week

love this product great charging device especially when traveling.

Nice device... eliminates 'fighting' for an outlet- at the airport, etc

Great little device.

and I cannot express how useful this little device is

I would try to be always charging my phone, my noise-canceling headphones, and sometimes other devices

Upon receiving my dissatisfaction email, Sunvalleytek promptly replaced the defective device with a new one that is working.

Two great things about this portable charger - 1) it holds its charge for a long, long time, and 2) it charges my devices FAST - as fast or faster than the "quick charge" wall wart that came with my Samsung Galaxy

Also being able to charge multiple devices at their optimum rate a great bonus as well.

This device worked perfectly

I will never be caught with a dead cell phone or device again.

I take this everywhere as advertised the problem is have so many electronic devices in the house someone always takes it, I would recommend if you have a full house order more than one.

Love this device

Lasts for weeks and is so reassuring when you travel internationally..protects your devices while charging.

Awesome device

Great device, when traveling my phone battery drains quickly, this is reliable, portable charging

Great device
