The author's Type B personality is so lax about battery life that he rarely leaves the house without a fully charged phone. The Podoru Magsafe Battery Pack, a portable power bank that magnetizes to the back of my cell phone, has enabled me to bring my dead phone beyond its 50-percent threshold and charge simultaneously. The battery pack also supports lightning charging and temperature control, overcharge protection, and short circuit protection. It works with most recent iPhone models, down to the iPhone 12. The small size and ability to power up multiple devices at once has been noted as a convenience. However, the power bank is only compatible with USB-C charging cables, and it's recommended only with a magsafe-compatible phone case.
