There have been plenty of obvious winners since the birth of the Pokemon Go craze, but one of the smarter plays may be an up-and-down maker of accessories for consumer electronics. Shares of ZAGG (ZAGG) soared 19% last week. The catalyst to the stock's pop was a bullish analyst note alluding to the volatile stock's prospects in light of Pokemon Go's success.

Roth Capital analyst Dave King raised his price target on ZAGG last week, going from $5 to $6 in light of the likely uptick in demand for its power management products. ZAGG's Power Amp products line offers portable phone charging solutions. This may not seem like a Pokemon Go play at first, but have you seen how smartphone batteries dry up in light of folks draining their devices when they fire up the app? Even with its power saver settings, Pokemon Go is a battery hog -- and that's where ZAGG Power Amp comes in.   

King believes that Pokemon Go's success could deliver a 15% spike to ZAGG's bottom line, following channel checks across 50 retail locations that show heightened demand for products that extend battery lives. ZAGG Power Amp isn't the only portable battery charger on the market. There's a glut of offerings, even at price points below the $30 suggested retail price of the entry-level Power Amp. However, this will be a rising tide that will lift all ships, and ZAGG happens to be a small enough publicly traded player where a bump in demand can move the needle. 

Crashing the third-party party

Roth Capital's analyst isn't necessarily bullish on ZAGG. King actually has a Neutral rating on the stock. Perhaps more importantly, ZAGG stock's 19% pop last week finds it poking its head above his $6 price target.

However, the continuing success of Pokemon Go will have a positive impact on ZAGG. King's move last week centers around ZAGG's portable battery chargers, but let's not forget about ZAGG's flagship screen protectors. The success of its InvisibleShield screens may not seem like a rider of Pikachu's coattails, but have you seen folks glued to their phones as they explore their surroundings? Smartphone owners will get careless. Phones will drop, and either screens will crack or folks spared shattered fates will spring on protecting their displays.

This was shaping up to be a mixed year for ZAGG. Analysts see a sharp spike in revenue, but have revised their profit targets lower in recent months. They now see bottom-line results falling short of last year's showing, and earnings have missed Wall Street expectations badly in back-to-back quarters. This makes the new Pokemon Go window of opportunity so important. ZAGG has had its ups and downs over the years, and this new break offers the chance to turn things around.
