When I travel for photography, I charge the laptop using a power inverter or battery source in my vehicle (I almost never stay in a hotel/motel). The rocky dirt roads are bumpy, the car is loaded up with gear; there is no flat table for the laptop to sit upon and charge in peace.
A pristine MagSafe connector port is bad enough—the thing just does not stay attached very well. But a troublsome flaw in the MagSafe design is that over time, small magnetic particles start attaching themselves inside the connector port on the laptop. I’ve had to dig out the larger particles with a knife blade, but always the very fine small ones are hard to get out. These particles exacerbate the hassles of an already too-loose connector, and so the darned charger plug is constantly coming off, which stops the laptop from charging. (The BatteryBox avoids this issue since it clips on, but it is not for charging).
Along comes a product I’d never have guessed existed: the NewerTech Snuglet. It’s a tiny little metal jacket that goes into the charging port. Two are included, and a tool is provided for removal (but I have no intention of removing it).
The NewerTech Snuglet just works. I am very pleased to have this problem-solver product; it kept my laptop power attached and charging on a recent trip. Fantastic!
