If you need to charge the ThinkPad X1 Carbon or Lenovo Yoga Or ThinkPad Helix in a car or on an airplane (it can be also used as a normal power adapter), you can use the Lenovo AC/DC Combo power adapter (90 Watts), and the Lenovo slim power tip. This setup is both compact (weighing around 0.35 kg for the entire setup, or 0.23 kg for the DC part), and energy efficient (conversion efficiency of over 95%).

I have recently noticed that Lenovo have increased their use of the new rectangular shaped power connector in the next series of ThinkPads that they are going to release this year (2013). If you haven’t seen the new power connector that i am talking about, have a look at the image below. For those whom do not know, the rectangular power connector first debuted in the ThinkPad X1 Carbon, for space saving reasons.

It has been a while since i have done a review (or semi0-review) of the Lenovo ThinkVision monitors, the last one i did was in May of 2012 (/blog/2012/05/08/lenovo-thinkvision-lt1421-review/). The LT1421 was a 14 inch HD portable USB LCD, which i particularly like due to the quality of construction and its design, but i was somewhat let down by the LT1421 lackluster 1366x720 resolution in a 14 inch LCD format. In addition, the TN panel used in the LT1421 was not very good in terms of viewing angle, gamut or contrast, since then i have been praying for a 1600x900 IPS version of this monitor to come to the market.

ThinkPad RapidCharge battery was first debuted in the ThinkPad X1 in 2011, it allowed the battery to be charged from flat to 80% within 30 minutes. This RapidCharge technology that Lenovo uses is different to the lithium rapid charge technology that most other companies use, which are based on using high voltage (to compensate for internatl resistances within the cells). The Lenovo RapidCharge technology is based on high current, which is apparently better for the battery longevity than the high voltage version of the rapid charge battery technology.
