Review: Just Mobile’s TopGum adds glam + a magnetic charging base to a 6,000mAh battery
The secret to understanding USB battery pricing is that you tend to get what you pay for: cheap batteries lose their charges faster and can bulge and leak over time. Other companies specialize in selling atypically nice batteries that last longer and work better. Just Mobile is a leader in quality batteries: for the past six years, its Gum series (shown below) has spanned every Apple device type, size, and speed, but it has never built a Lightning cable into a battery before. That changes with the January release of TopGum ($80), which advances the company’s prior state-of-the-art Gum++ model in two ways: an authentic Lightning cable’s integrated into the battery’s left edge, and a matching magnetic battery charging dock is included.
Of course, these features – and a choice of gold or gray metal exteriors – come at a premium over typical all-plastic batteries, so if you don’t need the cable or dock, you’ll be equally well-served with the company’s earlier batteries. Read on for the full story.
