It’s not daily that a brand-new entrant into the accessories market provides us with their whole exterior battery pack product, yet that held true with Tylt, a two year-old business that is making a splash with some nicely-designed gadgets.

Tylt Energi Portable Battery Packs

We got one of each of their Tylt Energi line of mobile battery packs, most of which feature an integrated charging arm. However the most exciting part of this line is the degree of certifications that each electric battery pack has actually caught, making them a rarity in a globe where it seems like everybody is making low-cost battery packs.

For TUAW viewers that will certainly be at Macworld/iWorld 2014 on Friday, March 28, make sure to visit the TUAW Meet Up at 4 PM PDT in area 131 at Moscone Center North Hall, as we’ll be handing out some of these great electric battery packs.

Layout Features

Possibly the 2 Tylt Energi versions that will be of the most interest to iOS fans are the 3K+ and 5K+. Why? These two have actually an attached Lightning charging arm; think of it as an integrated cable that is always with the electric battery pack. Of these 2, the 3K+ is best for charging an iPhone or iPod touch, including more than enough energy to recharge your iPhone greater than when. The 3K+ additionally has a vacant USB port, and the device could charge two apples iphone at the same time.

The 5K+ not simply has that Lightning charging arm, however likewise features a micro-USB billing arm and an empty USB port. It can handle an iPad, or as much as three iPhones at the same time.

Literally, the battery packs are fairly desirable, showcasing an usual design with a black instance and a shade (blue, grey or red) red stripe across the center. Every one of the packs except the 10K have a single LED condition indication– the 10K has five LEDs to show the relative battery degree of the pack.

Capability Features

I tried both the 3K+ and 5K+. The 3K+ charged up in regarding 3-1/2 hours from a fully released state, while the 5K+ took around 6-1/4 hours to bill up. All of the Energi packs feature a USB to micro-USB cable for billing objectives, although you’ll require to provide your very own AC to USB adapter.

The Lightning billing arm on both the 3K+ and 5K+ conceal in the sides of the battery pack when not being used, a great function because you don’t have to bother with having a wire tangling in your favored lugging bag.

Personally, I assume it’s interesting that Tylt has actually gone via the process to have the packs licensed. According to Tylt, “IEEE 1725 controls battery design, production, assembly, leakage security, overcharge, mechanical performance and quality assurance.” Tylt’s Energi line is additionally “certified to meet UL’s vast method for Lithium electric batteries called UL 1642.” The UN38.3 law makes sure the security of battery products on airplane and in other transportation, with the Energi products conference and exceeding “all 8 UN needs consisting of: Altitude, Thermal Examination, Vibration, Shock, External Short Circuit, Influence, Overcharge, and Forced Discharge.”

So exactly what does all of this certification rubbish provide for you? Tylt points out that they’re using the very same manufacturing and security requirements made use of by companies like Samsung and Apple. There’s no memory result on these batteries, which will offer you 500 full cycles of life. The mAh capacity is specifically as stated, and the batteries are ensured to work in extreme temperature levels. Finally, the firm supplies a 1 year warranty on the items since they’re so sure they’re likelying to run as marketed.

That’s a much cry from the much cheaper, however crooked electric battery packs we’ve viewed from some manufacturers. It’s terrific to view a firm that is ready to opt for top quality over price.


All external battery packs are not alike, and Tylt’s Energi line of battery packs is one of the very first we have actually seen that places performance and safety and security before low rate. That’s not to mention that the Energi packs are costly– some suppliers actually bill much more for packs with less pedigree. We consider the Energi loads to be amongst the top doing ones we’ve checked, and the 3K+ and 5K+ are ideal friends for your iPhone given that they feature an integrated Lightning charging arm.
