Two ways to charge the Switch 8

There are a couple ways to keep the Switch 8 charged up and ready to go. If you don't have access to a conventional source of power, you can connect the Switch 8 to one of Goal Zero's solar panels. Or, you can plug the Switch 8 into any USB power source, such as a laptop (takes about  4 hours to recharge). Four LEDs indicate the level of charging completed (while charging), and power availability (when not charging).

If you plan use the Switch 8 with a Goal Zero solar panel, check out the Switch 8 Solar Recharging Kit, which adds the ultra-compact Nomad 3.5 panel.

Better Than Nothing

BrianC from Crozet, VA on 11/6/2014

The day before I left for a plane trip, I stopped by Crutchfield to get noise cancelling headphones. As an afterthought, I bought this recharger to use enroute, if necessary, to buy some time until I could use my wall charger at my destination. I didn't need it, but tested it a little at the place I stayed (20 min.). I don't remember how much it charged then, but I still had 3 of the 4 lights lit on the charger when I got home. Ten days later (today), I still show 3 lights (75% recharger capacity). So the product holds a charge for a long time. Just for the heck of it, I connected the recharger to my Android phone, at 53% charge, for one hour. The result: the phone's charge got to 88%, and the recharger was down to 2 lights. In other words, it cost the recharger 25% to give the phone a 35% charge. This also conflicts with the company's specs, saying the recharger totally charges a phone in one hour; my experiment predicts almost 3 hours for a 100% charge.Compared to other portable rechargers, it's the smallest, lightest option out there. Unlike a few competitors out there, it doesn't get hot while it's being charged or charging a phone. So, was this worth the price I paid? For me, using only for a smartphone to buy some possibly precious time, yes.

Pros: Light, small, doesn't heat up, holds charge for long time, price

Cons: Long charging time


Hands-on research

Product Research


Overview: The Switch 8 portable recharger is a Lithium-ion (NMC) battery designed to charge or power small USB powered devices. The Switch 8 is charged using the included USB extension cable plugged into its male USB type-A input plug. It can be charged using a standard USB power supply or an optional Nomad solar panel. There are four LEDs to show the amount of charging completed (while charging) and power availability (when not charging). The Switch 8 turns on automatically when a USB powered device is plugged into its female USB type-A port. Multiple Switch 8s can be chained together (end to end); although this doesn't change the voltage, the total battery capacity is increased.
