Size Matters

When providing this much power you can expect a bulky and fairly heavy portable charger weighing in at 1.45 lbs or 657 grams. The outer shell is dual layered and made of a non slip anti shock rubber coating. The USB port covers snap firmly into place keeping your ports free of dust and debris, ready for all weather treks in any environment.

The ToughJuice has dual power buttons on each side of the device lit with a four LED indicator lights showing the batteries remaining charge.



How many times can I charge my phone? What to expect?

When using any decent external charger such as this one you might expect to be able to charge a 3000 mAh phone battery ten times based on the math that: 30,000÷3000 = 10. This is not typically the case with external battery packs. In the real world you would get about eight full charges. The best (rough estimate) way to factor how many charges you would get  is to always reduce your answer by 20%. So (30,000÷3000) – 20% = 8 for example. It is important to note manufacturers usually advertise laboratory condition tests. You should expect to get less than manufacture claims and expect your devices to use more than their its battery capacity when charging. ZeroLemon does advertise it will charge most smartphones 6-10 times and most tablets 2-3 times. This is an average estimate but will depend on your devices battery sizes.juice3-hover

The ZeroLemon ToughJuice portable battery is rugged, tough and one of the biggest quality built portable batteries available. It will easily survive extended drops without issue. I did notice this device does not have circuitry for “charge through” capability. This means you cannot charge your devices at the same time you are recharging the ToughJuice. You must charge the ToughJuice then charge your device. This may not be a big deal unless you happen to be charging it with a portable solar panel and want to charge your devices at the same time. This could be a hindrance in a situation such as that.

This is a great battery to carry in a backpack or carry-on luggage. It will definitely get you where you need to go without worry. It is heavy but the quality is superb and gives you the extra power where other portable batteries fall short. If you are in the market for a portable battery charger definitely check out ZeroLemon’s ToughJuice. You will not be disappointed.
