The ideal power bank should be large enough to ensure you never run out of juice, but small enough to carry with you everywhere. The 20,000mAh capacity of the Extreme Boost backup battery perfectly fits the bill, and it’s a whopping 63% off on Tech Deals right now.

Not only could you charge your standard smartphone four to five times with the Extreme Boost, but you can also charge four devices at once. The battery features four USB ports and Smart Charge Technology that adapts the charging speed to match each device. You can also match your battery to your tech with silver, black, and rose gold options.

Charging four devices at one time sounds like it would be a safety hazard, but the Extreme Boost packs plenty of safety features. It has overcharge, overcurrent, and short circuit protection to ensure you needn’t worry about damaging your device. The charging progress is displayed on a convenient LED indicator.
