Frequently Asked Questions

How much mAh do I need to recharge my phone?

For newer phones, you’ll likely need at least 3,000mAh to fully recharge a dead phone. However, the latest models need up to 5,000mAh or more to fully recharge. While phone chargers with more mAh can be used repeatedly before being drained, they often get bulkier the larger their capacity gets.

Are lithium polymer or lithium-ion batteries better?

Both lithium polymer and lithium-ion batteries are fantastic for portable devices. They each have their trade-offs, though. Lithium-ion batteries tend to last longer and are better at keeping a constant voltage. Lithium polymer batteries, however, are lighter, thinner, and even safer due to their design.
