Customer Ratings & Reviews

Was looking for a battery for my iPhone for when i travel. This was on sale for the same price as other brands with a lot less voltage. It was a little bulkier than i wanted originally, but i keep it in my back pack or bag and it's no problem. 12,000 volts and it works great. I get grief because it's a Tumi, but it will charge my phone about 5 times before i need to recharge it.

It's attractive, but took almost 14 hours to fully charge the first time, and it so heavy that you cannot stand it up for charging. It does charge a cell phone very fast, and we'll keep it on hand for power outages; because it is so large, it can only go in checked baggage. Now I will have to get a smaller one that can go in carry-on, just so I can charge on the go between terminals.

I was able to fully charge my iPhone 6 from around 10% to 100% under 2 hours. Quite handy. The charger looks pretty but a bit heavy. I tried to test it and charged my iPhone 6 five times over a few days and charger still not totally drained. Not bad.

I was at BB looking for Apple lightning cables when I came across the Tumi products. They were all 70% off, so it was a no-brainer. I needed a portable charging pack and this Tumi is sweet! Two USB ports and enough juice to charge a couple phones or an iPad...twice. It's stylish, like me, and looks great with my work portfolio and leather bag. Push the power button and you can see how much juice is left in the pack with white LEDs. Hold it for a couple seconds to power it on and off. I couldn't beat it for the price. If you can find one, BUY IT!

Great battery. Works great. Wish it was lighter. Great quality.

I know that there are probably better/cheaper options out there but I wanted a portable charger that was built to last and that was of superior quality. Tumi is a brand that I trust. I love the look/feel of the leather and so far the capacity of the charger has met my expectations.

It's a decent enough charger. I got it for a great price so I don't regret it. I do wish it was not as bulky nor heavy as it is now. It does have two USB ports to charge multiple devices and does a fast and good charge. I think the brand itself is good.

By far worth every penny spent. Charges devices fast, long battery life, can charge two devices at once. Downside : takes 3-4 hours to charge when you use the entire battery life.

I got this booster for work and it works great. It can charge multiple items at once or back to back. It charges quickly.

Love this device for recharging my tech devices. Works fast and very reliable.

Love the different amp outputs. Contemporary sleek design, heavy and tough.

I use this to charge electronics like phone and Kindle when camping, its great in that roll.

Perfect for travel. A little heavy, but I got it on sale and works wonderfully!

Awesome charger with great aesthetics and charges my portable devices quickly!

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.

Great charger for the price. I caught it on major sale. It is very convenient

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

This has been a great addition to our travel bag and is used all the time. Would highly recommend to those with the need to have additional power available when out and about, or on the road traveling. Excellent quality, and endurance for a pair of road warriors.

Having around 5 full iPhone 7 recharges in it, I've yet to run out of battery on either my phone or the charging brick. I travel a good bit outside of the country, so it's always helpful in getting multiple devices charged quickly when I only have one outlet converter, then recharging the Tumi brick overnight.

As a backup power supply the Tumi works and looks great -small and very stylish. I am just disappointed because Tumi advertises an app so that you can monitor the battery life from your phone but mine is either broken or does not have the functionality. If that worked it would definitely get a 5-star review.
