After attaching the connectors, you'll need to replace your battery and cover while wrapping the sticker around to the outside of your phone and affixing it to the rear face. Finally, connect the charging base to an electrical outlet before placing the phone on the base with the sticker facing down. If you've done everything correctly, your phone should start charging immediately. A green LED on the charging base will flash to show that charging is underway.
We tested the Spike Charger with a Sony Ericsson S710a and a Nokia 6131. Both phones started charging immediately but we noticed that that S710a couldn't charge all the way. That may have something to do with the phone but the battery meter never went above about 80 percent. Also, even when we knew the phone was receiving power, the S710's battery indicator never registered that as such. Fortunately, we had better luck with the Nokia handset. We were able to charge it all the way, and it took about the same amount of time as a standard charger. We didn't run full battery tests on either phone but each handset's charge seemed to last for a respectable period. Likewise, we didn't try using the Spike Charger on a completely dead battery.
Those issues aside, our main complaints center on the Spike Charger's design and setup. While you could place a phone anywhere on the WildCharger's base, the Spike Charger's base has a very specific charging point in its center. Unless you put your phone on that exact spot, the charging won't commence. Even when you place it in the correct position, the slightest touch will suspend charging. Indeed, when we left the Spike Charger for a couple of hours we noticed it would turn off at unexplained moments. Moreover, we weren't crazy about affixing a sticker to our phone. Not only is a bit unsightly, but also we just don't like applying an adhesive to any of our gadgets. It didn't leave any marks, and we could remove it when not in use, but it's still a bit unsightly.
The setup process also is rather clumsy. Depending on the shape of your phone's battery and the fit of the battery cover, it can be difficult to place everything correctly. Particularly on the S710a, we had to play with the sticker for a few moments to attach it securely. And even once we got it right, the whole arrangement was still rather cumbersome. On the upside, the sticker will work with more than one model of cell phone. In comparison, the WildCharger is compatible only with the Motorola Razr V3.
Sure, we had a few complaints, but the Spike Charger does accomplish what it sets out to do. Eeven better, Wizdex says it is designing a new model that will ditch the sticker entirely. Instead it says it is working with a few manufacturers to embed the Spike Charger technology directly into phone batteries. We'll wait for that product to give the Spike Charger our most sincere endorsement.
