Using the TYLT Energi 2K Battery Pack
For my time with the TYLT Energi 2K Battery Pack, I had my Galaxy S5 to charge up to 100%. With a 2800mAh internal battery in my Galaxy S5, and a 2000mAh battery in the Energi 2K, it meant that I couldn't recharge my smartphone back to full charge. But, I knew this going into it - and so will you if you end up purchasing the Energi 2K. What I was able to do, is go out of the house knowing that I have ~75% charge in my pocket for my S5, or if I let it deflate down to 50%, I could have it back to 100% in no time.
This is how I used the charger, so I went out to the shops for some lunch and a haircut with my Energi 2K in my pocket, and my Galaxy S5 at 46%. While I was walking around trying to keep my 3-year-old daughter from running into people and becoming a stealth shoplifter (by picking up things she walks past), I had my Galaxy S5 on charge, sitting in the baby pusher with my nearly 5-month-old daughter. By the time we were finished having lunch and about to head back to the car, my Galaxy S5 was fully charged back to 100% for me to use for the rest of the afternoon, and night.
I found the TYLT Energi 2K Battery Pack a joy to use, but one of the downsides is that it doesn't feature an embedded micro-USB to USB cable that the slightly bigger Energi 3K comes with. This has major repercussions, as it means you have to tote around a micro-USB to USB cable if you want to use the Energi 2K. I wish it was just a little thicker so that TYLT could've primed the Energi 2K with the embedded USB cable, especially as it is so portable. Also consider that the Energi 3K isn't that much bigger, but has not only the embedded USB cable, but 1000mAh more battery too.
It's So Small!: I can comfortably hold the TYLT Energi 2K Battery Pack in my hand, as it is much smaller than any smartphone I have in my lab (and I have a lot). This is great, as TYLT has a tiny, tiny charger in the Energi 2K. It really is just so small, and packs quite a punch with its tiny frame with its internal 2000mAh lithium ion battery.
It Looks Great: The style continues over from the Energi 3K Battery Pack, with the Energi 2K featuring a beautiful small look. We have the same LED button on the side, too. The red and black theme looks great, so if you're a fan of that color scheme, you should grab it. Remember that there is the blue version, and gray version.
No Embedded micro-USB cable: This is a letdown, it's something we really wanted to see included.
It's a Tad Expensive: At $39.99, it's just too expensive. If it were priced at $29.99, or even better - at $19.99 - then we'd be talking. There are cheaper batteries on the market that offer much more power in something that is - yes, larger - but it's not like we're talking four times the size. Something like the LUXA2 EnerG 8800mAh Portable Battery Bank is a better buy. TYLT has its market in the way that the Energi 2K is just super small, something that will very easily fit into your pocket, but you pay a bit of a premium for that.
What we have today is a well-rounded, small and light portable battery bank that is a little on the expensive side. If TYLT had adjusted the Energi 2K so that it had an embedded USB cable, and a cheaper price, at say $19.99 for the Energi 2K and $29.99 for the 3K, then we'd be talking. What TYLT has here is a great charger that is a little expensive. But, it is super small (slightly thicker and wider than a 2.5-inch SSD) charger that can easily top up any smartphone you have to nearly 100%.
This is one of the harder final thoughts I've had in a while, as I'm truly torn. I love the design of the Energi 2K, the packaging, the less-than-a-handful that it is, but it's the embedded USB cable not being present and the price that stops this from getting a higher score. I think what TYLT has is two very different batteries, with the Energi 2K being the entry-level charger, while the slightly bigger, $10 more Energi 3K featuring the awesome embedded USB cable.
If you're in the market for one of the smallest portable batteries, TYLT has a great offering in its Energi 2K. But, I think you should seriously consider, and probably buy the Energi 3K over this, as it is $10 more, comes with a larger battery, and comes with an embedded USB cable, which makes all the difference for its overall portability configuration.
