The TYLT ENERGI 5K+ battery pack [$89] is slim (9/16″), yet has enough juice to triple your phone’s battery capacity. It has built-in Lightning & Micro-USB Cables and has a Universal USB Port. It can charge 3 devices with its 5,200mAh internal battery. Tylt has built a reputation for producing innovative and reliable products and the 5K+ Energi battery pack lives up to that reputation like a champ. The 5K+ is great for those of us who live houses divided and have both iOS and Android devices. It’s the first battery pack I’ve seen with both cables built in. It’s like the Ying Yang of chargers, striking the perfect harmonious balance.
