Juice on the Go for your Smart Phones and Mobile Devices

These days, a smartphone is an indispensable tool for a serious shooter. Smartphones can forecast the weather, direct you to the range, map your terrain, calculate your ballistics, photograph your targets, and even measure wind velocity (with a $35.00 plug-in impeller).

Having all those capabilities is great… until your battery goes flat. Even the most advanced smartphone on the planet is nothing but a useless paperweight when you run out of juice. Thankfully there’s an affordable fix for that problem — back-up Li-ion battery packs with built-in solar chargers.

There are a variety of external power-packs on the market, some with solar panels, some without. These will charge smartphones, tablets, PDAs, and other mobile devices. We like the units with solar chargers because they can recover a little energy when you’re outdoors. You still need to plug them in to get a full charge BEFORE before you head to the range. But once fully charged, these back-up battery devices can get your smartphone back in action and keep it running all day long.

We like the Poweradd portable chargers*. These feature lithium-ion batteries, solar panels, and tough weatherproof shells. We’ve tried two models, the 8000 mAh Apollo 3 ($29.99, dual-port), and the original 7200 mAh Apollo ($19.99, single port). We purchased the 7200 mAh Poweradd (Photo above) before its third-generation bigger brother was offered. The original 7200 mAh Apollo has served us well. It can fully charge most smartphones a couple times, or smaller tablets once. As long as you make sure the Poweradd is fully charged before you leave home (since the solar charger is slow and secondary), this unit does everything it claims. This editor’s first-generation Poweradd Apollo has done yeoman duty for many months now. It has revived both an iPhone and a tablet. If I were to purchase a Poweradd unit now, I would get the Apollo 3, mainly because it offers two (2) charging ports compared to one (1) on the original Apollo. That lets you charge two devices at once.

* If you need even more power, consider the Poweradd Pro. This 23000 mAh powerpack offers Multi-Voltage (5V 12V 16V 19V) output, and has enough juice to run a modern laptop. It comes with a complete set of jacks/cables so it can work with almost any device. This kind of capability doesn’t come cheap — the Poweradd Pro sells for $109.99, more than five times the cost of our 7200 mAh Apollo.
