Customer Ratings & Reviews

Haven't used it much but it works great so far. It's a great size and packs a lot of backup power.

I have had many mobile charging devices, this is the best by far.

This is a great battery backup that is also professional in appearance. Tumi is a luxurious brand.

I charged My phone several times throughout my travels and I noticed this charges fast!

Very compact and practical for someone to needs power at time where you can't find any.

This is the 3rd one I bought over the last 12 months; catch it when it is on sale.

Great for what it's for does charge my phone a couple of times and I can also charge my iPad with it. However it is really heavy and big which makes it difficult to carry around in a purse. I would recommend it for long trips where no outlet is available but not for carrying around in your purse or bag.

I got this on sale and it works great! It is very convenient for traveling.

Sleek device for the professional on the go who needs extra juice on hand.

Great to have. A little heavy but well worth the weight. Great purchase

A bit bulky and doesn't come with clip. Otherwise great value.

very nice and durable looks good and it is Tumi price is good

This charger great for travel. Was convenient and easy to use

I like the Tumi items. The charger will come in handy!

The charger takes a while to charge and it's a bit bulky. However, I like the 12,000 mAh battery

Apple charging cords don't always work which defeats the purpose of the charger

Stopped working after 5 months, but since I’m always working and I work nights I didn’t bother to return it.
